Product details
Overview
TLV2625ID from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier with shutdown control, designed for low-power, wide-bandwidth signal conditioning in single-supply systems. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, 27 nV/√Hz input voltage noise, 800 µA/channel supply current, and operates from 2.7 V to 5.5 V across –40°C to 125°C - ideal for high-resolution data acquisition interfacing with SAR ADCs.
For engineers reviewing the TLV2625ID datasheet, TLV2625ID pinout, TLV2625ID application, or TLV2625ID equivalent, key selection criteria include its quad-channel SOIC-16 package with independent 1/2SHDN and 3/4SHDN pins, ultralow 4 µA/channel shutdown current, rail-to-rail output swing, and positive-rail-inclusive input common-mode range (1 V to VDD + 0.2 V).
Technical Context
The TLV2625ID implements a CMOS input stage enabling picoampere-level input bias current (2 pA typ) and rail-to-rail output swing using complementary output transistors. Its internal architecture supports stable unity-gain operation with 63° phase margin into 2 kΩ || 10 pF loads, and features dual independent shutdown controls: Pin 8 (1/2SHDN) disables Channels 1 & 2, Pin 9 (3/4SHDN) disables Channels 3 & 4.
It is specified for industrial temperature operation (–40°C to 125°C) with input offset voltage of 3500 µV max at 25°C and 4500 µV max over full temperature range, and maintains 75 dB minimum PSRR and 82 dB minimum CMRR at 25°C under 2.7 V supply - critical for precision sensor front-ends powered by Li-ion cells.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-signal conditioning without board-level channel duplication |
| GBW | 11 MHz - supports >1 MSPS sampling in driving 16-bit SAR ADCs with minimal settling error |
| Slew Rate | 10 V/µs - ensures faithful reproduction of fast transient signals up to ~1.6 MHz full-power bandwidth |
| Supply Current | 800 µA/channel - allows battery-powered portable instrumentation with >100-hour runtime on 200 mAh cell |
| Shutdown Current | 4 µA/channel - reduces system standby power by >99% per disabled amplifier pair |
| Input Noise | 27 nV/√Hz @ 10 kHz - preserves SNR in low-amplitude sensor amplification (e.g., thermopile, bridge outputs) |
| Common-Mode Range | 1 V to VDD + 0.2 V - permits direct interface to VDD-referenced sensors and DACs without level-shifting |
Pinout & Package
TLV2625ID is housed in a 16-pin SOIC (D) package with 1.27 mm pitch, 10.3 mm body width, and RoHS-compliant green (Pb-free, no Sb/Br) CU NIPDAU finish. Moisture sensitivity level is Level-1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier 1 output - rail-to-rail swing supports full dynamic range utilization of downstream ADC |
| 2 | 1IN− | Inverting input of Amp 1 - high impedance (100 GΩ) minimizes loading on high-Z sources like piezoelectric sensors |
| 3 | 1IN+ | Non-inverting input of Amp 1 - accepts common-mode voltages up to VDD + 0.2 V for direct VDD-referenced biasing |
| 4 | GND | Analog ground reference - shared return path for all four amplifiers; requires low-impedance PCB plane |
| 5 | VDD | Positive supply rail - accepts 2.7 V to 5.5 V; decoupling capacitor mandatory at pin for stability |
| 6 | 2IN+ | Non-inverting input of Amp 2 - identical VIH/VIL thresholds as Amp 1 for consistent multi-channel design |
| 7 | 2IN− | Inverting input of Amp 2 - matched to Pin 2 for common-mode rejection in differential configurations |
| 8 | 1/2SHDN | Shutdown control for Amps 1 & 2 - logic-low (<0.4 V) disables both; high-Z state must be avoided |
| 9 | 3/4SHDN | Shutdown control for Amps 3 & 4 - independent of Pin 8, enabling selective channel power gating |
| 10 | 3IN− | Inverting input of Amp 3 - electrically isolated from Amps 1 & 2 to prevent crosstalk in mixed-signal routing |
| 11 | 3IN+ | Non-inverting input of Amp 3 - supports same VICR and biasing schemes as Pins 3 and 6 |
| 12 | 3OUT | Amplifier 3 output - pin-compatible with Pin 1 for layout reuse in quad-channel filter banks |
| 13 | 4OUT | Amplifier 4 output - rail-to-rail drive capability ensures compatibility with 3.3 V logic interfaces |
| 14 | 4IN− | Inverting input of Amp 4 - matched input capacitance (8 pF) to all other inputs for balanced AC response |
| 15 | 4IN+ | Non-inverting input of Amp 4 - enables unity-gain buffer configuration without external components |
| 16 | 4OUT | Amplifier 4 output - note: datasheet confirms Pin 16 is 4OUT (not NC); corrects common misreading of D-package top view |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 260 mV of rails at 10 mA load - maximizes ADC input range and dynamic headroom |

| Dual independent shutdown | Pins 8 and 9 enable granular power management - e.g., disable unused channels during low-power sleep modes |
| Low input bias current | 2 pA typical - prevents significant DC error when amplifying high-impedance sources (>1 MΩ) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2624IDR | Same family, quad-channel, but lacks independent 3/4SHDN control - uses single SHDN pin for all channels | Less flexible power sequencing; unsuitable for partial-channel shutdown architectures | Select TLV2624IDR only if unified shutdown suffices and PCB layout rework is prohibitive |
| OPA4340UA | Higher precision (125 µV VIO max), lower noise (16 nV/√Hz), but higher supply current (750 µA/channel vs. 800 µA) and no shutdown | Preferred for ultra-low-error metrology; not viable for battery-powered systems requiring standby mode | Choose OPA4340UA when offset and noise dominate over power; avoid when shutdown functionality is mandatory |
Compared with TLV2624IDR, TLV2625ID offers superior power management granularity via dual SHDN pins, while versus OPA4340UA it trades minor noise/offset performance for essential shutdown capability and broader supply range - making TLV2625ID optimal for energy-constrained, multi-channel industrial sensing.

FAQ
What is the operating temperature range for TLV2625ID?
The TLV2625ID is rated for industrial-grade operation from –40°C to +125°C. This specification is guaranteed across all electrical parameters in the datasheet, including input offset voltage, CMRR, and supply current - making TLV2625ID suitable for under-hood automotive modules, factory-floor PLCs, and outdoor environmental monitors where ambient extremes are expected.
Does TLV2625ID support true rail-to-rail input?
No, TLV2625ID does not support rail-to-rail input. Its common-mode input voltage range is specified as 1 V to VDD + 0.2 V - meaning the input cannot go below 1 V (relative to GND) but *does* extend 0.2 V beyond VDD. This "beyond-the-rail" capability enables direct interfacing with VDD-referenced sources, though a negative input swing requires external level shifting or biasing.
How many independent shutdown controls does TLV2625ID provide?
TLV2625ID provides two independent shutdown controls: Pin 8 (1/2SHDN) disables Amplifiers 1 and 2, while Pin 9 (3/4SHDN) disables Amplifiers 3 and 4. Each control accepts logic-low (<0.4 V) to enter shutdown (IDD(SHDN) = 4 µA/channel), and logic-high (>2 V) to enable. This dual-control architecture enables selective channel power gating - a capability absent in the pin-compatible TLV2624IDR.
What is the maximum capacitive load TLV2625ID can drive while maintaining stability?
TLV2625ID is characterized for stability with up to 10 pF capacitive load when driving a 2 kΩ resistive load (RL = 2 kΩ || CL = 10 pF), delivering 63° phase margin. Driving larger capacitive loads (e.g., >20 pF) risks peaking or oscillation unless compensated with a series resistor (e.g., 10–50 Ω) placed close to the output pin - a standard practice for driving ADC input capacitors or long PCB traces.
Is TLV2625ID compatible with 1.8 V supply rails?
No, TLV2625ID is not compatible with 1.8 V supply rails. Its absolute minimum supply voltage is 2.7 V, and operation below this violates recommended conditions and may result in undefined behavior, reduced output swing, or failure to meet AC specifications such as GBW and slew rate. For 1.8 V systems, consider TI's TLV2784 or similar 1.8-V–optimized quad op-amps.
