Product details
Overview
LTC1410CG#TRPBF from Analog Devices (formerly Linear Technology) is a 12-bit, 1.25 Msps successive-approximation ADC with differential input sample-and-hold, internal ±15 ppm/°C reference, and dual shutdown modes (Nap: 7 mW, Sleep: 10 µW). It delivers 71 dB S/(N + D) and 82 dB THD at 625 kHz Nyquist frequency, operating from ±5 V supplies in a 28-pin SO Wide package for high-speed data acquisition systems.
For engineers reviewing the LTC1410CG#TRPBF datasheet, LTC1410CG#TRPBF pinout, LTC1410CG#TRPBF application, or LTC1410CG#TRPBF equivalent, key selection criteria include its 20 MHz full-power bandwidth, ±1 LSB INL/DNL over temperature, no pipeline delay, true differential input architecture with 60 dB CMRR, and µP-compatible parallel interface with BUSY/CONVST/RD control signals.
Technical Context
The LTC1410CG#TRPBF implements a capacitor-based successive approximation register (SAR) architecture with integrated differential sample-and-hold, eliminating external timing components. Its internal clock is factory-trimmed to guarantee ≤750 ns conversion time and ≤800 ns throughput across 0°C to 70°C.
It supports bipolar ±2.5 V analog input range with true differential acquisition (±AIN), enabling common-mode noise rejection without external amplifiers. The device uses separate analog (AGND), digital logic (DGND), and output driver (OGND) grounds, and requires 10 µF tantalum + 0.1 µF ceramic bypassing on VREF, AVDD, DVDD, and VSS per datasheet layout guidelines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit with no missing codes - guarantees monotonic transfer function for precision measurement. |
| Sampling Rate | 1.25 Msps maximum - enables real-time capture of signals up to 625 kHz Nyquist frequency. |
| S/(N + D) | 71 dB at 600 kHz - ensures ≥11.5 effective bits for high-fidelity spectral analysis. |
| THD | –82 dB at 600 kHz - minimizes harmonic contamination in wideband signal conditioning. |
| INL / DNL | ±1 LSB max over temperature - preserves absolute accuracy in closed-loop control and calibration systems. |
| Full-Power Bandwidth | 20 MHz - supports undersampling of RF IF signals while maintaining SNR integrity. |
| Power Modes | Nap (7 mW) and Sleep (10 µW) - reduces system power by >95% during idle intervals without losing configuration. |
Pinout & Package
Package: 28-lead plastic SO Wide (SW), 0.300-inch body width, RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +AIN (1) | Differential analog input positive | Accepts ±2.5 V input; sampled simultaneously with –AIN for common-mode rejection. |
| –AIN (2) | Differential analog input negative | Enables ground-sense or true differential measurement; defines common-mode voltage point. |
| VREF (3) | Internal reference output | 2.500 V ±20 mV buffered output; can be overdriven for external reference use (2.25–2.75 V). |
| REFCOMP (4) | Reference amplifier compensation | Requires 10 µF tantalum + 0.1 µF ceramic to AGND for stability and low-noise operation. |
| AGND (5) | Analog ground reference | Single-point star ground for all analog circuitry; must be isolated from digital return paths. |
| D11–D4 (6–13) | MSB-aligned parallel data outputs | Three-state, TTL/CMOS-compatible; driven only when CS = RD = LOW. |
| DGND (14) | Digital logic ground | Tied to AGND; supplies internal control logic and SAR core. |
| D3–D0 (15–18) | LSB-aligned parallel data outputs | Completes 12-bit word; same timing and drive strength as D11–D4. |
| OGND (19) | Output driver ground | Separate return for output buffers; tied to AGND to minimize digital switching noise coupling. |
| NAP/SLP (20) | Shutdown mode select | HIGH = Nap mode (fast wake-up, 200 ns); LOW = Sleep mode (ultra-low power, 10 µW). |
| SHDN (21) | Shutdown enable | Active-low input; asserts selected Nap/Sleep mode when pulled LOW. |
| RD (22) | Data read strobe | Enables output drivers when CS is LOW; data valid on rising edge of BUSY. |
| CONVST (23) | Conversion start | Falling-edge triggered; initiates acquisition and conversion sequence with no pipeline latency. |
| CS (24) | Chip select | Must be LOW to accept CONVST and RD commands; disables outputs when HIGH. |
| BUSY (25) | Conversion status indicator | LOW during conversion; rising edge marks data validity and end of 800 ns throughput cycle. |
| VSS (26) | Negative supply rail | –5 V ±0.25 V; requires local 10 µF + 0.1 µF bypass to AGND. |
| DVDD (27) | Digital positive supply | +5 V ±0.25 V; shorted internally to AVDD (Pin 28) in standard configuration. |
| AVDD (28) | Analog positive supply | +5 V ±0.25 V; bypassed separately with 10 µF + 0.1 µF to AGND for analog integrity. |
Key Features
| Feature | Design Value |
|---|---|
| True differential input architecture | 60 dB common-mode rejection up to 100 kHz enables direct connection to noisy sensor bridges without external instrumentation amps. |
| No pipeline delay | Immediate data availability after BUSY rise eliminates FIFO buffering and simplifies real-time control loop timing. |
| Integrated 2.5 V reference | ±15 ppm/°C tempco and 0.01 LSB/V line regulation ensure stable full-scale span across industrial temperature range. |
| 20 MHz full-power bandwidth | Supports undersampling of IF signals (e.g., 2–5 MHz) in communications receivers while preserving ENOB > 11. |
| Three independent ground pins | AGND/DGND/OGND separation prevents digital switching noise from degrading analog acquisition fidelity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed SAR ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADS8505IPW | 16-bit, 250 ksps, single-ended input, external reference required | Higher resolution but lower speed; lacks differential input and internal reference | Select for DC-precision applications where throughput < 300 ksps suffices and external reference design is acceptable. |
| AD7865BSZ-1 | 14-bit, 100 ksps, quad-channel, parallel interface, ±5 V supplies | Slower, multi-channel, no Nap/Sleep modes; requires external reference and clock | Choose when simultaneous sampling of four analog signals is needed and power optimization is secondary. |
Compared with ADS8505IPW and AD7865BSZ-1, the LTC1410CG#TRPBF uniquely combines 1.25 Msps speed, integrated reference, differential input, and dual shutdown modes in a single 28-pin SOIC - making it optimal for compact, battery-aware, wideband acquisition where board space and supply simplicity are critical.

FAQ
What is the operating temperature range for the LTC1410CG#TRPBF?
The LTC1410CG#TRPBF is specified for the commercial temperature range of 0°C to 70°C. This is indicated by the "C" suffix in the part number and confirmed in the Absolute Maximum Ratings table, where LTC1410C denotes the 0°C to 70°C grade. The device maintains ±1 LSB INL/DNL and 71 dB S/(N + D) across this full range.
Does the LTC1410CG#TRPBF require an external clock source?
No, the LTC1410CG#TRPBF does not require an external clock. It contains a fully integrated, factory-trimmed internal clock that guarantees ≤750 ns conversion time and 1.25 Msps sampling rate across temperature. The internal clock eliminates synchronization complexity with microprocessor control signals and removes the need for external timing components.
Can the LTC1410CG#TRPBF operate with a single +5 V supply?
No, the LTC1410CG#TRPBF requires dual ±5 V supplies (AVDD = DVDD = +5 V, VSS = –5 V) as specified in the Power Requirements section. Its analog input range is ±2.5 V, and absolute maximum ratings define VSS down to –6 V. Operation with single supply is not supported and would violate the device's bipolar architecture and internal reference design.
How does the NAP/SLP pin affect power consumption of the LTC1410CG#TRPBF?
The NAP/SLP pin selects between two shutdown modes: when HIGH, SHDN activation enters Nap mode (7 mW typical); when LOW, SHDN activation enters Sleep mode (10 µW typical). Both modes retain register state and allow fast wake-up - Nap mode recovers in 200 ns, Sleep mode in <1 µs - enabling dynamic power scaling in burst-mode acquisition systems using the LTC1410CG#TRPBF.
Is the LTC1410CG#TRPBF pin-compatible with other variants in the LTC1410 family?
Yes, the LTC1410CG#TRPBF shares identical pinout and footprint with all 28-pin SO Wide variants (e.g., LTC1410CSW, LTC1410IG, LTC1410ISW). The "G" suffix denotes the SO Wide package, and the "C" denotes commercial temperature grade. Electrical specifications differ by grade (C vs I), but mechanical compatibility and signal routing are preserved across all SW-package LTC1410 devices.
