Product details
Overview
LTC1410IG#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1.25 Msps successive-approximation ADC with differential input, internal ±2.5V bipolar full-scale range, 71 dB S/(N+D) at 625 kHz, ±1 LSB INL/DNL over temperature, and no pipeline delay. 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, high-dynamic-range digitization of analog sensor or RF IF signals.
For engineers reviewing the LTC1410IG#TRPBF datasheet, LTC1410IG#TRPBF pinout, LTC1410IG#TRPBF application, or LTC1410IG#TRPBF equivalent, key selection considerations include its 20 MHz full-power bandwidth, dual shutdown modes (7 mW Nap / 10 µW Sleep), true differential input CMRR ≥60 dB, and guaranteed 800 ns throughput time across –40°C to +85°C industrial temperature range.
Technical Context
The LTC1410IG#TRPBF employs a capacitor-based successive approximation register (SAR) architecture with an internal differential sample-and-hold front-end, enabling simultaneous acquisition of ±AIN inputs with 50–100 ns acquisition time and <5 psRMS aperture jitter. Its internal 2.5 V bandgap reference features ±15 ppm/°C tempco and supports external reference override via VREF pin.
Digital interface uses asynchronous control logic with separate CONVST (edge-triggered), BUSY (data-ready flag), CS (chip select), and RD (output enable) signals - delivering deterministic timing: 650–750 ns conversion time, 40 ns minimum CONVST pulse width, and 15–50 ns data access window depending on load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function for precise control loop feedback. |
| Sampling Rate | 1.25 Msps maximum - supports Nyquist-limited signal capture up to 625 kHz with full AC performance. |
| S/(N + D) | 71 dB at 600 kHz input - enables >11.5 ENOB for demanding spectrum analysis and communications IF sampling. |
| INL / DNL | ±1 LSB max over –40°C to +85°C - ensures accurate DC measurement and linearity-critical calibration applications. |
| Full-Scale Input Range | ±2.5 V differential - matches standard op-amp output swing and simplifies anti-alias filter design. |
| Power Dissipation | 160 mW active; 7 mW in Nap mode; 10 µW in Sleep mode - enables battery-backed or thermally constrained embedded systems. |
| Aperture Jitter | 5 psRMS - limits SNR degradation at high input frequencies, critical for undersampling applications. |
Pinout & Package
Package: 28-pin SO Wide (SW), RoHS-compliant, body width 7.6 mm, thermal resistance θJA = 95°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +AIN (1) | Differential analog input positive | Accepts ±2.5 V input; sampled simultaneously with –AIN; requires matched trace routing for optimal CMRR. |
| –AIN (2) | Differential analog input negative | Enables common-mode noise rejection; can serve as local ground sense for single-ended sources. |
| VREF (3) | 2.5 V reference output | Factory-trimmed bandgap source; buffered; supports external override between 2.25 V and 2.75 V. |
| REFCOMP (4) | Reference amplifier compensation | Must be bypassed to AGND with 10 µF tantalum || 0.1 µF ceramic for stability and low-noise operation. |
| AGND (5) | Analog ground reference | Single-point star ground for all analog circuitry; isolated from digital grounds per layout best practice. |
| D11–D4 (6–13) | MSB-aligned parallel data outputs | Three-state, TTL/CMOS compatible; D11 = MSB; driven only when CS = RD = LOW and BUSY = HIGH. |
| DGND (14) | Digital logic ground | Tied to AGND at single point; separates internal logic switching noise from analog section. |
| D3–D0 (15–18) | LSB-aligned parallel data outputs | Completes 12-bit word; D0 = LSB; same timing and drive characteristics as D11–D4. |
| OGND (19) | Output driver ground | Separate return for output buffers; minimizes ground bounce during bus transitions. |
| NAP/SLP (20) | Shutdown mode select | High = Nap mode (fast wake-up, 7 mW); Low = Sleep mode (ultra-low power, 10 µW). |
| SHDN (21) | Power shutdown enable | Active-low; initiates selected shutdown mode when asserted; wake-up time ≤200 ns from Sleep. |
| RD (22) | Data read strobe | Enables output drivers when CS is low; data valid on rising edge of BUSY, not RD edge. |
| CONVST (23) | Conversion start trigger | Falling-edge sensitive; starts SAR cycle; must remain low ≥40 ns; retriggering mid-conversion causes errors. |
| CS (24) | Chip select | Active-low enable for CONVST and RD recognition; required for microprocessor interfacing. |
| BUSY (25) | Conversion status indicator | Active-low open-drain output; goes high at end of conversion; rising edge marks data validity. |
| VSS (26) | Negative supply (–5 V) | Bypassed to AGND with 10 µF || 0.1 µF; absolute max –6 V; supports rail-to-rail analog input swing. |
| DVDD (27) | Positive digital supply (5 V) | Shorted internally to AVDD; supplies digital logic and output drivers; bypassed identically to AVDD. |
| AVDD (28) | Positive analog supply (5 V) | Bypassed to AGND with 10 µF || 0.1 µF; powers sample-and-hold, reference, and SAR core. |
Key Features

|---|---|
| True differential input architecture | 60 dB common-mode rejection up to 1 MHz - eliminates ground loops and enables direct connection to transformer-coupled or floating sensors. |
| No pipeline delay | Deterministic 800 ns total throughput - enables real-time closed-loop control without latency-induced instability. |
| Integrated 2.5 V reference | ±15 ppm/°C tempco and ±0.02 V initial accuracy - removes need for external reference IC and reduces BOM count. |
| 20 MHz full-power bandwidth | Supports undersampling of IF signals beyond Nyquist - allows direct digitization of 10–20 MHz bandpass signals in communications receivers. |
| Two-tier shutdown control | Configurable Nap (7 mW, 200 ns wake-up) and Sleep (10 µW, 200 ns wake-up) - optimizes power vs responsiveness trade-off in burst-mode systems. |

FAQ
What is the operating temperature range of the LTC1410IG#TRPBF?
The LTC1410IG#TRPBF is rated for industrial temperature operation from –40°C to +85°C. This range is explicitly specified in the Absolute Maximum Ratings table and confirmed across all AC and DC performance parameters marked with the "G" symbol in the datasheet, including ±1 LSB INL/DNL, 71 dB S/(N+D), and 1.25 Msps sampling rate.
Does the LTC1410IG#TRPBF require external components for basic operation?
No, the LTC1410IG#TRPBF requires no external components for core functionality: it integrates a precision 2.5 V reference, sample-and-hold, internal clock, and reference buffer. Only mandatory external elements are bypass capacitors - 10 µF tantalum || 0.1 µF ceramic on VDD, VSS, and REFCOMP pins - as specified in the Typical Application schematic and Layout Guidelines.
How does the LTC1410IG#TRPBF handle common-mode noise on its analog inputs?
The LTC1410IG#TRPBF achieves ≥60 dB common-mode rejection ratio (CMRR) up to 1 MHz via its fully differential input sample-and-hold stage. This allows it to reject noise coupled equally onto +AIN and –AIN traces - such as ground loops or EMI - while preserving the differential signal. Layout best practice requires matched-length, side-by-side routing of both inputs.
What is the wake-up time from Sleep mode for the LTC1410IG#TRPBF?
The wake-up time from Sleep mode for the LTC1410IG#TRPBF is guaranteed ≤200 ns after SHDN is de-asserted (driven high), as specified in the Timing Characteristics table under parameter t4. This fast recovery enables use in burst-mode acquisition systems where power cycling occurs between individual samples or frames.
Can the LTC1410IG#TRPBF be used with an external reference?
Yes, the LTC1410IG#TRPBF supports external reference operation: the VREF pin (Pin 3) accepts an externally sourced voltage between 2.25 V and 2.75 V, overriding the internal 2.5 V reference. This is documented in the Applications Information section and validated by Figure 8b showing LT1019A-2.5 as a compatible external reference IC.
