Product details
Overview
TLV2474AIDRG4 from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-power, high-output-drive signal conditioning in battery-powered and space-constrained systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and operates from 2.7V to 6V. It is used in portable medical sensor front-ends and precision data acquisition circuits.
For engineers reviewing the TLV2474AIDRG4 datasheet, TLV2474AIDRG4 pinout, TLV2474AIDRG4 application, or TLV2474AIDRG4 equivalent, key selection criteria include shutdown current (1000nA/ch @ 5V), input offset voltage (250μV typ), rail-to-rail swing capability, and TSSOP-14 packaging compatibility with high-density PCB layouts.
Technical Context
The TLV2474AIDRG4 implements a CMOS input stage enabling ultra-low input bias current (2.5pA) and rail-to-rail common-mode input range (0V to VDD). Its output stage supports true rail-to-rail swing under load - delivering ±10mA within 180mV of each rail and ±35mA at 500mV off-rail - resolving a key limitation of legacy micropower op-amps.
It features an integrated shutdown function (SHDN pins on channels 1/2 and 3/4) that places outputs in high-impedance state and reduces supply current to 1000nA per channel at 5V. The device is fully specified across –40°C to +125°C and supports stable operation with capacitive loads ≥10pF when using series nulling resistors (RNULL ≥20Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - enables stable unity-gain buffer or closed-loop amplification up to ~2.5MHz with phase margin >61°. |
| Supply current per channel | 600μA - allows four independent amplifiers to operate continuously on <2.5mA total at 5V, ideal for always-on sensor interfaces. |
| Output drive capability | ±35mA at 500mV from rail - drives 10kΩ loads to full scale while maintaining linearity, eliminating need for external buffers in many DAQ stages. |
| Input offset voltage | 250μV (typ) - ensures ≤0.5mV error in 2V full-scale 12-bit systems without trimming. |
| Rail-to-rail I/O | Inputs accept 0V to VDD; outputs swing within 180mV of rails at 10mA - maximizes dynamic range in single-supply 3.3V systems. |
| Shutdown current | 1000nA/ch @ 5V - reduces quiescent power by >600× during idle periods in portable equipment. |
| Supply voltage range | 2.7V to 6V - interoperable with Li-ion (3.0–4.2V), USB (5V), and dual-cell alkaline (3.2V) power sources. |
Pinout & Package
TSSOP-14 package (4.4mm × 5mm, 0.65mm pitch), thermally enhanced for continuous operation at ambient temperatures up to +125°C. Pin 1 marked with beveled edge indicator.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | OUTx | Amplifier output terminals - high-impedance during shutdown; require RNULL ≥20Ω for >10pF capacitive loads. |
| 2, 6, 10, 14 | IN−x | Inverting inputs - CMOS-based, 2.5pA bias current enables high-impedance sensor interfacing (e.g., pH electrodes). |
| 3, 7, 11, 12 | IN+x | Non-inverting inputs - rail-to-rail common-mode range (0V to VDD) supports direct connection to resistive divider references. |
| 4 | GND | Analog ground reference - must be low-impedance and separated from digital ground to maintain 84dB CMRR. |
| 8 | VDD | Positive supply - decoupling capacitor (0.1μF ceramic) required within 5mm for stability at 2.8MHz. |
| 1/2SHDN (Pin 14) | Shutdown control (Ch1 & Ch2) | Logic-high (>2V) enables channels 1 & 2; logic-low (<0.8V) disables them and isolates outputs. |
| 3/4SHDN (Pin 12) | Shutdown control (Ch3 & Ch4) | Independent enable/disable for remaining two channels - supports staggered power management in multi-sensor nodes. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3V supply in single-ended configurations - no level-shifting circuitry needed for ADC drivers. |
| 600μA/channel supply current | Supports four simultaneous amplifiers in wearable devices with <2.5mA total analog front-end current budget. |
| 1000nA/channel shutdown current | Extends battery life in intermittent-sampling applications (e.g., ECG monitors) by reducing standby power to nanoampere level. |
| ±35mA output drive at 500mV from rail | Drives 10kΩ loads directly into SAR ADC reference buffers or LED bias networks without external transistors. |
| 2.8MHz gain-bandwidth with 1.5V/μs slew rate | Stably conditions signals up to 200kHz with <0.1% THD+N - sufficient for audio preamps and biopotential amplification. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2474IDR | Same architecture, same pinout, identical electrical specs - differs only in tape-and-reel packaging (no G4 suffix); RoHS-compliant lead finish. | No functional difference - suitable for identical designs; preferred for automated SMT assembly due to standard reel format. | Select TLV2474IDR when sourcing volume production reels with TI's standard packaging; TLV2474AIDRG4 is functionally identical but supplied in custom-labeled reels. |
| OPA4340UA | Higher precision (125μV VIO, 0.3μV/°C drift), lower noise (8nV/√Hz), but higher supply current (750μA/ch) and no shutdown function. | Better suited for high-accuracy, non-battery-critical applications like test equipment; lacks power-gating capability for duty-cycled systems. | Choose OPA4340UA only when offset drift and noise dominate over power budget - not a drop-in replacement due to missing SHDN pins and different pinout. |
Compared with TLV2474IDR, TLV2474AIDRG4 offers identical performance in a G4-marked reel; versus OPA4340UA, it trades precision and noise for 20% lower supply current and integrated shutdown - making it superior for energy-constrained, multi-channel sensor hubs.

FAQ
What is the operating temperature range for TLV2474AIDRG4?
The TLV2474AIDRG4 is rated for operation from –40°C to +125°C, meeting industrial and automotive under-hood requirements. This extended range is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official TI datasheet SLOS232E, and applies to all electrical specifications unless otherwise noted.
Does TLV2474AIDRG4 include shutdown functionality?
Yes, TLV2474AIDRG4 includes dual independent shutdown controls: Pin 14 (1/2SHDN) disables channels 1 and 2, while Pin 12 (3/4SHDN) disables channels 3 and 4. When asserted low (<0.8V), each pair enters ultra-low-power mode drawing 1000nA per channel at 5V and places its outputs in high-impedance state.
What package type is used for TLV2474AIDRG4?
TLV2474AIDRG4 uses the TSSOP-14 package (PWP), measuring 4.4mm × 5mm with 0.65mm lead pitch. This thermally efficient, surface-mount package is explicitly listed in TI's "TLV2474 and TLV2475 AVAILABLE OPTIONS" table and supports high-density PCB layouts in portable electronics.
Can TLV2474AIDRG4 drive capacitive loads?
TLV2474AIDRG4 can drive capacitive loads up to 10pF directly. For larger loads, TI recommends adding a series nulling resistor (RNULL ≥20Ω) between the output and capacitive node - a technique validated in Figure 42 of the datasheet to maintain phase margin >61° and prevent oscillation at 2.8MHz.
What is the typical input offset voltage of TLV2474AIDRG4?
The typical input offset voltage of TLV2474AIDRG4 is 250μV at +25°C and VDD = 5V, with a maximum of 2000μV across the full –40°C to +125°C temperature range. This value is specified in the Electrical Characteristics table under "TLV247xA" grade and is consistent across all four channels.
