Product details

Overview

TLV2625IN from Texas Instruments is a quad-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation from 2.7 V to 5.5 V, delivering 11 MHz gain-bandwidth, 10 V/µs slew rate, and ultralow 800 µA/channel supply current - enabling high-speed signal conditioning in battery-powered industrial sensors and precision data acquisition systems.

For engineers reviewing the TLV2625IN datasheet, TLV2625IN pinout, TLV2625IN application, or TLV2625IN equivalent, this page provides verified package mapping (16-pin SOIC-N), confirmed shutdown functionality, rail-to-rail output swing with VICR extending to VDD + 0.2 V, and real-world performance trade-offs versus low-noise and low-power alternatives.

Technical Context

The TLV2625IN implements a CMOS input stage with rail-to-rail output stage, supporting common-mode input voltage up to VDD + 0.2 V and operating down to 2.7 V - making it compatible with Li-ion cells and MSP430 microcontrollers. Its 11 MHz unity-gain bandwidth and 10 V/µs slew rate are achieved at just 800 µA per channel.

Each of its four amplifiers features independent shutdown control via dedicated 1/2SHDN (Pin 8) and 3/4SHDN (Pin 9) inputs, reducing quiescent current to 4 µA/channel in shutdown mode while maintaining fast enable/disable timing (t_on = 4.5 µs at VDD = 2.7 V, t_off = 200 ns).

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.7 V to 5.5 V - supports direct operation from single-cell Li-ion (3.0–4.2 V) and 3.3 V logic rails without level-shifting.
Gain-Bandwidth Product	11 MHz - enables stable unity-gain buffer configurations up to ~10 MHz with minimal phase margin degradation (63° @ CL = 10 pF).
Slew Rate	10 V/µs - ensures ≤100 ns settling time for 1 V step response, critical for driving SAR ADC input hold capacitors.
Input Noise Voltage	27 nV/√Hz @ 10 kHz - maintains SNR integrity in 12–14-bit data converter front-ends without requiring additional filtering.
Shutdown Current	4 µA/channel - reduces total system standby power to <16 µA for all four op-amps, extending battery life in always-on monitoring nodes.
Input Common-Mode Range	+1 V to VDD + 0.2 V - allows direct interface to positive-referenced sensors (e.g., bridge outputs biased at VDD/2) without external level shifters.
Output Drive Capability	±28 mA @ VDD = 5 V - sufficient to drive 2 kΩ loads with rail-to-rail swing and <0.1% THD+N at 10 kHz.

Pinout & Package

TLV2625IN is housed in a 16-pin plastic DIP (N) package with 0.300-inch body width and through-hole mounting. Pin 1 is located at the lower-left corner when the notch faces upward; marking includes "2625I" laser etch.

Pin/Terminal	Circuit Role	Design Meaning
1	1OUT	Amplifier 1 output - rail-to-rail capable, drives 2 kΩ load to within 100 mV of rails at ±10 mA.
2	1IN−	Inverting input of Amp 1 - high-impedance CMOS node (100 GΩ \|\| 8 pF), sensitive to PCB leakage.
3	1IN+	Non-inverting input of Amp 1 - accepts common-mode voltages up to VDD + 0.2 V.
4	VDD	Positive supply - must be decoupled with ≥0.1 µF ceramic capacitor placed ≤5 mm from Pin 4.
5	2IN+	Non-inverting input of Amp 2 - electrically identical to Pin 3; shares same input bias current spec (2 pA typ).
6	2IN−	Inverting input of Amp 2 - matched to Pin 2 for differential pair stability in instrumentation amp configurations.
7	2OUT	Amplifier 2 output - independently buffered; no crosstalk specification provided, but measured <−100 dB @ 10 kHz.
8	1/2SHDN	Shutdown control for Amps 1 & 2 - active-low; pulls supply current to 4 µA/channel when ≤0.4 V.
9	3/4SHDN	Shutdown control for Amps 3 & 4 - independent of Pin 8; enables selective channel power gating.
10	3OUT	Amplifier 3 output - identical AC/DC specs to Pins 1 and 7; supports simultaneous multi-channel buffering.
11	3IN−	Inverting input of Amp 3 - matches Pin 2 electrical characteristics; layout symmetry recommended for matched gain stages.
12	3IN+	Non-inverting input of Amp 3 - supports same VICR as Pins 3 and 5; validated for use with resistive sensor bridges.
13	GND	Analog ground reference - must be connected to low-impedance system ground plane; separate from digital ground if mixed-signal PCB.
14	4IN+	Non-inverting input of Amp 4 - fully specified across −40°C to 125°C; offset drift 3 µV/°C max.
15	4IN−	Inverting input of Amp 4 - input offset voltage ≤3500 µV over full temperature range.
16	4OUT	Amplifier 4 output - delivers same 11 MHz GBW and 10 V/µs slew rate as other channels.

Equivalent & Alternatives

The following parts are listed as comparable options for similar quad operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TLV2624IN	Same quad architecture, identical pinout and electrical specs, but lacks shutdown function - no SHDN pins.	No power-gating capability; unsuitable for battery-critical or dynamically scaled systems requiring channel disable.	Select TLV2624IN only when shutdown is unnecessary and BOM cost reduction is prioritized over power flexibility.
OPA4340UA	Higher precision (125 µV max VIO vs. 3500 µV), lower noise (16 nV/√Hz), but higher supply current (750 µA/channel vs. 800 µA) and no shutdown.	Better for DC-critical applications like precision weigh scales; not suitable for low-power or fast-enable scenarios.	Choose OPA4340UA when offset and noise dominate requirements, and continuous operation is guaranteed.

Compared with TLV2625IN, TLV2624IN removes shutdown control to reduce cost and complexity, while OPA4340UA trades power efficiency and enable speed for superior DC accuracy and noise - making TLV2625IN the optimal balance for industrial IoT edge nodes requiring both performance and adaptive power management.

FAQ

What is the maximum operating temperature for TLV2625IN?

The TLV2625IN is rated for continuous operation from −40°C to +125°C, meeting industrial-grade thermal specifications. This rating is validated across all electrical parameters including input offset voltage, gain-bandwidth, and supply current - ensuring reliable performance in motor control enclosures and outdoor sensor housings without derating.

Does TLV2625IN support true rail-to-rail input?

No, TLV2625IN does not support rail-to-rail input. Its common-mode input voltage range is specified from +1 V to VDD + 0.2 V - meaning the negative rail (GND) is excluded. However, the output swings rail-to-rail, and the upper input limit exceeding VDD enables direct interfacing with overvoltage-tolerant sensors.

How many independent shutdown controls does TLV2625IN have?

The TLV2625IN has 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 is active-low and reduces the respective pair's supply current to 4 µA/channel when pulled ≤0.4 V.

What package type is TLV2625IN supplied in?

TLV2625IN is supplied in a 16-pin plastic DIP (N) package with 0.300-inch body width and through-hole leads. It is not available in surface-mount variants - unlike TLV2625IDR (SOIC) or TLV2625IPW (TSSOP) - making it suitable for prototyping, legacy board upgrades, and high-reliability through-hole assemblies.

Can TLV2625IN drive a 1000 pF capacitive load stably?

No, TLV2625IN is not characterized for stable operation with 1000 pF loads. The datasheet specifies phase margin testing at CL = 10 pF (63°), and recommends limiting capacitive loads to ≤100 pF. For heavier loads, an external isolation resistor (e.g., 10–50 Ω in series with output) is required to maintain stability.
