Product details
Overview
TLV2625IDR from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for low-power, wide-bandwidth single-supply operation. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, and 27 nV/√Hz input voltage noise at 800 µA per channel supply current, operating from 2.7 V to 5.5 V across –40°C to 125°C. It is used in high-resolution data acquisition front-ends interfacing with SAR ADCs.
For engineers reviewing the TLV2625IDR datasheet, TLV2625IDR pinout, TLV2625IDR application, or TLV2625IDR equivalent, key selection criteria include its rail-to-rail output swing, positive-rail-inclusive input common-mode range (1 V to VDD + 0.2 V), ultralow shutdown current (4 µA/channel), and SOIC-14 package compatibility with industrial temperature-grade signal conditioning designs.
Technical Context
The TLV2625IDR implements a CMOS input stage enabling rail-to-rail output swing and VICR extending to the positive supply rail-critical for direct interfacing with unipolar sensor outputs and reference-based systems. Its 11-MHz unity-gain bandwidth and 10-V/µs slew rate support stable closed-loop operation up to ~1 MHz with 2-kΩ load and 10-pF capacitive load.
Shutdown control is implemented via two dedicated pins (Pin 8: 1/2SHDN; Pin 9: 3/4SHDN), allowing independent power gating of amplifier pairs. The device maintains phase margin ≥63° under recommended conditions (RL = 2 kΩ, CL = 10 pF), ensuring robust stability without external compensation.
Key Specifications

|---|---|
| Gain-bandwidth product | 11 MHz - Enables stable unity-gain buffer or gain-of-10 amplification up to ~1.1 MHz with adequate phase margin. |
| Slew rate | 10 V/µs - Supports full-scale step response for 12-bit+ ADC drivers with ≤100-ns settling to 0.1%. |
| Supply current per channel | 800 µA - Allows four amplifiers to operate within 3.2 mA total, suitable for battery-powered instrumentation. |
| Input voltage noise | 27 nV/√Hz @ 1 kHz - Minimizes contribution to system noise floor in precision sensor signal chains. |
| Common-mode input range | 1 V to VDD + 0.2 V - Accepts inputs referenced directly to VDD, eliminating level-shifting in rail-sensing applications. |

Pinout & Package
TLV2625IDR is housed in a 14-pin SOIC (D) package with 1.27-mm pitch, 8.65-mm body width, and RoHS-compliant NiPdAu lead finish. It features dual shutdown control and quad-amplifier topology with non-overlapping pin assignments for signal isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of amplifier A - Rail-to-rail swing supports full dynamic range utilization into 2-kΩ loads. |
| 2 | 1IN− | Inverting input of amplifier A - High-impedance CMOS node (100 GΩ) minimizes loading on feedback networks. |
| 3 | 1IN+ | Non-inverting input of amplifier A - Accepts common-mode voltages up to VDD + 0.2 V for direct VDD-referenced sensing. |
| 4 | VDD | Positive supply rail - Shared by all four amplifiers; requires local 100-nF ceramic decoupling. |
| 5 | 2IN+ | Non-inverting input of amplifier B - Electrically isolated from amplifier A inputs to prevent crosstalk. |
| 6 | 2IN− | Inverting input of amplifier B - Matches impedance and layout symmetry with Pin 2 for matched gain configurations. |
| 7 | 2OUT | Output of amplifier B - Independent output driver enables parallel or differential output configurations. |
| 8 | 1/2SHDN | Shutdown control for amplifiers A and B - Logic-low (≤0.4 V) disables both channels; rise/fall times <200 ns. |
| 9 | 3/4SHDN | Shutdown control for amplifiers C and D - Independent of Pin 8, enabling selective channel power management. |
| 10 | 3OUT | Output of amplifier C - Maintains same AC performance as Pins 1 and 7 under identical load conditions. |
| 11 | 3IN− | Inverting input of amplifier C - Internally isolated; no shared substrate path with other amplifier inputs. |
| 12 | 3IN+ | Non-inverting input of amplifier C - Supports same VICR and bias current specs as Pins 2 and 3. |
| 13 | GND | Analog ground reference - Single ground pin serves all four amplifiers; requires low-impedance PCB connection. |
| 14 | 4OUT | Output of amplifier D - Final output in quad configuration; matches DC accuracy and noise specs of other outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 26 mV of rails at 1-mA load, preserving full ADC input range in 3.3-V systems. |
| Positive-rail-inclusive input range | Accepts signals up to VDD + 0.2 V, enabling direct interface with resistive sensor bridges biased at VDD. |
| Dual independent shutdown control | Pins 8 and 9 allow selective disabling of amplifier pairs-reducing power without redesigning signal routing. |
| Low input bias current | 2 pA typical - Prevents voltage error in high-impedance transducer interfaces (e.g., piezoelectric sensors). |
| Industrial temperature grade | Specified over –40°C to 125°C with no parameter derating-eliminates thermal validation overhead in harsh environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2624IDR | Same family, identical pinout and electrical specs; differs only in part marking and packaging logistics (same SOIC-14 reel format). | No functional difference; TLV2624IDR is the base quad variant without shutdown control-lacks SHDN pins 8 and 9. | Select TLV2624IDR only if shutdown functionality is unnecessary and board layout must remain unchanged. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C offset drift), lower input offset (2 µV max), but lower GBW (350 kHz) and higher supply current (17 µA/channel). | Better DC precision for thermocouple amplification; unsuitable for >100-kHz signal paths due to limited bandwidth. | Choose OPA2333AIDR when microvolt-level DC stability dominates over speed; avoid for ADC driver roles requiring >1-MHz bandwidth. |
Compared with TLV2624IDR, TLV2625IDR adds dual shutdown capability without altering footprint or DC specs-enabling dynamic power scaling. Versus OPA2333AIDR, TLV2625IDR trades DC precision for 31× higher bandwidth and 21× lower quiescent current, making it optimal for speed- and power-constrained signal chains.

FAQ
What is the maximum recommended supply voltage for TLV2625IDR?
The absolute maximum supply voltage for TLV2625IDR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operation at 5.5 V is fully specified across –40°C to 125°C, supporting lithium-ion battery systems and 5-V industrial rails. Exceeding 5.5 V risks permanent damage and voids warranty compliance.
Does TLV2625IDR support true rail-to-rail input operation?
TLV2625IDR does not support rail-to-rail *input*-its common-mode input voltage range is specified from 1 V to VDD + 0.2 V. While the output swings rail-to-rail, the input cannot accept signals at GND. This design enables high-speed CMOS input stages while maintaining stability and low input bias current.
How does the shutdown function work on TLV2625IDR?
TLV2625IDR uses two dedicated shutdown pins: Pin 8 (1/2SHDN) controls amplifiers A and B; Pin 9 (3/4SHDN) controls amplifiers C and D. Driving either pin to ≤0.4 V disables the corresponding pair, reducing supply current per channel to 4 µA. Both pins must be high (>2 V) to enable all four amplifiers.
Can TLV2625IDR drive a 1000-pF capacitive load stably?
TLV2625IDR is characterized for stability with up to 10 pF capacitive load (RL = 2 kΩ). Driving 1000 pF directly will cause severe peaking and potential oscillation due to reduced phase margin. For heavy capacitive loads, use a series resistor (≥100 Ω) between output and load, or add an external isolation buffer stage.
Is TLV2625IDR pin-compatible with other TLV262x variants in SOIC-14?
Yes-TLV2625IDR shares identical SOIC-14 pinout and footprint with TLV2624IDR. However, TLV2624IDR lacks shutdown pins (8 and 9 are NC), so using TLV2625IDR in a TLV2624IDR-designed board requires verifying that Pins 8 and 9 are either left unconnected or actively driven to logic high to enable all channels.
