Product details
Overview
LTC1410ISW#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1.25 Msps successive-approximation ADC with differential input, internal ±2.5V bipolar range, 71 dB S/(N+D) at Nyquist, and dual shutdown modes (7 mW Nap, 10 µW Sleep). It integrates a precision 2.5 V reference, sample-and-hold, and µP-compatible parallel interface - used in high-speed data acquisition systems requiring low-latency, no-pipeline-delay conversion.
For engineers reviewing the LTC1410ISW#TRPBF datasheet, LTC1410ISW#TRPBF pinout, LTC1410ISW#TRPBF application, or LTC1410ISW#TRPBF equivalent, key selection criteria include its 20 MHz full-power bandwidth, ±1 LSB INL/DNL over temperature, true differential input architecture with 60 dB CMRR, and compatibility with ±5 V supplies for telecom and DSP signal chain designs.
Technical Context
The LTC1410ISW#TRPBF employs a capacitor-based successive approximation register (SAR) architecture with an integrated differential sample-and-hold front-end. Its analog core operates with ±5 V supplies, supports both internal (15 ppm/°C) and external reference inputs, and delivers conversion results without pipeline delay - output data is valid on the rising edge of BUSY.
Digital interface timing is synchronized via CS, CONVST (active-low conversion trigger), and RD (data read enable), enabling direct connection to FIFOs, DSPs, and microprocessors. The device features three-state parallel outputs (D11–D0), separate BUSY status signaling, and two hardware-controlled power states selected by NAP/SLP and SHDN pins.

Pinout & Package
Package: 28-pin SO Wide (SW), RoHS-compliant, surface-mount plastic package with 0.3-inch body width and standard JEDEC outline.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +AIN (1) | Differential analog input positive | Accepts ±2.5 V input; sampled simultaneously with –AIN to enable true differential acquisition and common-mode noise rejection. |
| –AIN (2) | Differential analog input negative | Reference point for +AIN; enables ground-sense configurations and eliminates need for single-ended-to-differential conversion stages. |
| VREF (3) | Internal reference output | 2.500 V ±20 mV buffered output; can be overdriven with external reference (2.25–2.75 V) for span adjustment. |
| REFCOMP (4) | Reference amplifier compensation | Requires 10 µF tantalum || 0.1 µF ceramic bypass to AGND - critical for reference stability and low-noise performance. |
| AGND (5) | Analog ground reference | Single-point star ground for all analog circuitry; must be isolated from digital grounds to prevent coupling into sensitive SAR core. |
| D11–D4 (6–13) | MSB-aligned parallel data outputs | Three-state, TTL/CMOS-compatible outputs; active when CS = LOW and RD = LOW - supports memory-mapped µP interfacing. |
| DGND (14) | Digital logic ground | Ground return for internal control logic; tied to AGND externally to minimize ground bounce between analog and digital domains. |
| D3–D0 (15–18) | LSB-aligned parallel data outputs | Completes 12-bit word (D11–D0); same timing and drive characteristics as D11–D4 - simplifies PCB routing for wide bus. |
| OGND (19) | Output driver ground | Separate ground for output buffers; improves noise immunity of data bus by isolating switching currents from core logic. |
| NAP/SLP (20) | Shutdown mode select | HIGH selects Nap mode (fast wake-up); LOW selects Sleep mode (ultra-low power) - determines behavior of SHDN pin. |
| SHDN (21) | Power shutdown enable | Active-low control; initiates selected shutdown state (Nap or Sleep) - reduces supply current to ≤2.3 mA or ≤100 µA respectively. |
| RD (22) | Data read strobe | Enables output drivers when CS is LOW; data valid after t10 (15–50 ns depending on load) following RD assertion. |
| CONVST (23) | Conversion start trigger | Falling-edge initiated; starts SAR cycle and resets register - must remain LOW ≥40 ns; timing-critical for deterministic latency. |
| CS (24) | Chip select | Active-low enable for CONVST and RD recognition; required LOW during conversion and read cycles - prevents spurious command latching. |
| BUSY (25) | Conversion status indicator | Active-low open-drain output; goes HIGH at end of conversion - rising edge marks valid data availability on D11–D0. |
| VSS (26) | Negative supply rail | –5 V ±0.25 V supply; requires local 10 µF || 0.1 µF bypass to AGND - critical for analog section PSRR and THD performance. |
| DVDD (27) | Digital positive supply | +5 V ±0.25 V supply for logic and output drivers; shorted to AVDD per layout guidelines to minimize supply splitting. |
| AVDD (28) | Analog positive supply | +5 V ±0.25 V supply for SAR core and reference; bypassed with 10 µF || 0.1 µF to AGND - defines analog dynamic range and noise floor. |
Key Features
| Feature | Design Value |
|---|---|
| No pipeline delay | Conversion result appears on D11–D0 immediately after BUSY rises - eliminates latency uncertainty in real-time control loops. |
| True differential input | Simultaneous sampling of +AIN and –AIN with 60 dB CMRR - enables rejection of cable-borne noise in motor control and medical sensor interfaces. |
| Integrated 2.5 V reference | Factory-trimmed 15 ppm/°C bandgap reference with REFCOMP pin - removes need for external voltage reference IC and associated layout complexity. |
| 20 MHz full-power bandwidth | Supports undersampling of RF/IF signals up to 20 MHz - useful in SDR, spectrum analyzers, and broadband test equipment front ends. |
| Three-state parallel interface | Compatible with standard µP buses without glue logic - simplifies integration with legacy 8051, ARM7, or FPGA-based controllers. |
| Two-stage shutdown | Nap mode (7 mW) retains fast wake-up capability; Sleep mode (10 µW) maximizes battery life in portable instrumentation and IoT edge nodes. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD7892BRZ-1 | 12-bit, 1.5 Msps, ±5 V input range, no internal reference, requires external REF - higher power (250 mW), no shutdown modes. | Best suited for systems already using precision external references and needing marginally higher speed; lacks integrated reference and low-power flexibility. | Select when external reference control is required and board space permits discrete reference design; avoid if minimizing BOM count or power budget is critical. |
| MAX1190ECM+ | 12-bit, 1.25 Msps, single-ended input only, internal reference, 10 µW shutdown - lower CMRR (50 dB), no differential input capability. | Ideal for cost-sensitive, space-constrained applications with single-ended sensors; unsuitable for noise-prone differential signal paths or ground-isolated measurements. | Choose for simple unipolar sensor interfaces where differential noise rejection is unnecessary; not recommended for telecom or high-EMI industrial environments. |

FAQ
What is the maximum sampling rate supported by the LTC1410ISW#TRPBF?
The LTC1410ISW#TRPBF supports a guaranteed maximum sampling rate of 1.25 Msps across its full industrial temperature range (–40°C to +85°C). This rate is enabled by its 800 ns guaranteed throughput time (acquisition + conversion), and the device maintains 71 dB S/(N+D) and ±1 LSB linearity at this speed - making LTC1410ISW#TRPBF suitable for real-time digitization of signals up to 625 kHz (Nyquist frequency).
Does the LTC1410ISW#TRPBF require external components for basic operation?
No, the LTC1410ISW#TRPBF requires no external components for core functionality: it integrates a precision 2.5 V reference, sample-and-hold, and internal clock. Only mandatory external elements are bypass capacitors - 10 µF tantalum || 0.1 µF ceramic on VDD, VSS, and REFCOMP - to ensure stability and noise performance. All other functions, including power shutdown and digital interface, operate with direct pin control, confirming LTC1410ISW#TRPBF as a self-contained, easy-to-deploy ADC solution.
How does the differential input architecture of the LTC1410ISW#TRPBF improve noise immunity?
The LTC1410ISW#TRPBF achieves 60 dB common-mode rejection ratio (CMRR) through its true differential input stage, which samples +AIN and –AIN simultaneously. This allows rejection of noise coupled equally onto both traces - such as ground loops, EMI, or power supply ripple - while preserving the differential signal of interest. In practice, this means LTC1410ISW#TRPBF can accurately digitize small signals in electrically noisy environments (e.g., motor drives or industrial PLCs) without additional instrumentation amplifiers or filtering stages.
What are the power consumption values for each shutdown mode of the LTC1410ISW#TRPBF?
In Nap mode (SHDN = LOW, NAP/SLP = HIGH), the LTC1410ISW#TRPBF draws 1.5–2.3 mA from ±5 V supplies, totaling ~7–12 mW. In Sleep mode (SHDN = LOW, NAP/SLP = LOW), it consumes 1–100 µA per supply, resulting in ~0.01–1 mW total power. Both modes retain register state and allow wake-up in ≤200 ns via CONVST - enabling LTC1410ISW#TRPBF to meet stringent energy budgets in battery-powered instrumentation and portable test equipment.
Can the LTC1410ISW#TRPBF operate with an external reference, and what is the acceptable voltage range?
Yes, the LTC1410ISW#TRPBF supports external reference input via the VREF pin, which accepts voltages from 2.25 V to 2.75 V. Operation within this range ensures specified linearity (±1 LSB INL/DNL) and full-scale accuracy. Driving VREF with a precision external source - such as the LT1019A-2.5 - allows gain calibration, temperature drift reduction, or custom input span scaling. The internal reference remains disabled when an external source is applied, confirming LTC1410ISW#TRPBF's flexibility in high-accuracy metrology applications.
