Product details

Overview

TLV2624IPW 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, 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 - enabling use in precision signal conditioning stages of battery-powered data acquisition systems.

For engineers reviewing the TLV2624IPW datasheet, TLV2624IPW pinout, TLV2624IPW application, or TLV2624IPW equivalent, this page provides verified functional specifications, TSSOP-14 package layout, industrial-grade temperature performance, shutdown control timing (t_on = 4.5 µs at 2.7 V), and direct alternatives for rail-to-rail, low-noise, quad opamp replacement in space-constrained designs.

Technical Context

The TLV2624IPW integrates four independent amplifiers with shared shutdown control via pins 8 (1/2SHDN) and 9 (3/4SHDN), supporting selective channel enable/disable. Its CMOS input stage achieves 1 pA typical input bias current and common-mode input range extending to V_DD + 0.2 V, allowing direct interfacing with positive-rail-referenced sensors.

Designed for stability with 2 kΩ load and 10 pF capacitive load, it maintains 63° phase margin and 11 MHz unity-gain bandwidth while consuming only 800 µA per channel - achieving high-speed performance without compromising ultralow power operation in Li-ion powered systems.

9	3/4SHDN	Active-low shutdown control for Amps 3 & 4 - independent of Pin 8 for flexible power sequencing.
10	4OUT	Amplifier 4 output - shares same electrical specs as Pins 1 and 7; usable as composite output stage.
11	4IN−	Inverting input of Amp 4 - referenced to GND; no internal connection to other inputs.
12	4IN+	Non-inverting input of Amp 4 - supports single-ended or differential input configurations.
13	GND	Analog ground - must be connected to low-impedance PCB ground plane; separate from digital ground.
14	3OUT	Amplifier 3 output - fully specified for 2 kΩ load and 10 pF capacitance; stable without external compensation.

Key Features

Feature	Design Value
Rail-to-rail output swing	Drives within 100 mV of V_DD and GND at 10 mA load - maximizes ADC input range in 3.3 V systems.
Input common-mode range includes V_DD	Accepts signals up to V_DD + 0.2 V - eliminates level-shifting circuitry for sensors referenced to V_DD.

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	SOIC-14 package (8.65 mm × 3.91 mm); higher θ_JA (176°C/W vs. 173.6°C/W); same electrical specs.	Preferred for through-hole prototyping or legacy board compatibility; larger footprint limits density.	Select TLV2624IDR when manual soldering or socket-based testing is required; TLV2624IPW preferred for automated SMT volume production.
TLV2784IPW	Narrower supply range (1.8–3.6 V); lower bandwidth (8 MHz); higher input noise (9 nV/√Hz); same TSSOP-14 package.	Better suited for ultra-low-voltage (e.g., coin-cell) systems where 2.7 V minimum is insufficient.	Choose TLV2784IPW only if operating below 2.7 V is mandatory; TLV2624IPW provides superior speed/noise trade-off above 2.7 V.

Compared with TLV2624IDR and TLV2784IPW, the TLV2624IPW uniquely balances 11 MHz bandwidth, 27 nV/√Hz noise, and 2.7 V operation in the smallest surface-mount package - making it optimal for high-density, battery-powered instrumentation where performance-per-mm² matters.

FAQ

What is the maximum capacitive load the TLV2624IPW can drive while maintaining stability?

The TLV2624IPW is characterized for stable operation with 10 pF capacitive load and 2 kΩ resistive load, delivering 63° phase margin per channel. Driving >10 pF requires external isolation resistor (e.g., 10–50 Ω in series with output) to prevent peaking or oscillation - confirmed in Figure 16 of the SLOS251D datasheet.

Does the TLV2624IPW support true single-supply operation with input signals at V_DD?

Yes. The TLV2624IPW features a common-mode input voltage range extending to V_DD + 0.2 V, enabling direct interface with sensors or DACs referenced to the positive supply rail - eliminating need for external biasing networks in single-supply topologies.

How does shutdown timing behave across voltage and temperature for the TLV2624IPW?

At V_DD = 2.7 V, t_on = 4.5 µs (typical); at V_DD = 5 V, t_on = 1.5 µs. Turnoff time t_off is 200 ns (typical) across –40°C to 125°C. These values are measured from SHDN logic transition to 50% of final supply current, per Section 6.7 of the datasheet.

Can the TLV2624IPW be used in unity-gain stable configurations without external compensation?

Yes. The TLV2624IPW is unity-gain stable with 2 kΩ load and 10 pF capacitive load, achieving 63° phase margin. No external compensation components are required for standard voltage-follower or inverting amplifier configurations per the "Stability" section of the datasheet.

What is the output current capability of each amplifier in the TLV2624IPW?

Each amplifier delivers ±28 mA output current into loads where output voltage remains ≥0.5 V from either rail (V_DD or GND). This is specified at V_DD = 5 V; at 2.7 V, sourcing capability is ±14 mA - sufficient for driving ADC reference buffers and moderate-impedance filters.
