Product details
Overview
TLV2634IPWR from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier optimized for single-supply operation from 2.7 V to 5.5 V. It delivers 9 MHz gain-bandwidth, 730 µA per channel supply current, and ground-sensing input range (VICR = GND to VDD − 1 V), enabling direct interfacing with ground-referenced sensors in battery-powered data acquisition systems.
For engineers reviewing the TLV2634IPWR datasheet, TLV2634IPWR pinout, TLV2634IPWR application, or TLV2634IPWR equivalent, this page provides verified specifications, TSSOP-14 package terminal mapping, industrial-grade (−40°C to 125°C) performance data, and validated alternative op-amps for low-voltage, high-bandwidth signal conditioning designs.
Technical Context
The TLV2634IPWR implements a voltage-feedback architecture with unity-gain stable compensation, supporting rail-to-rail output swing while maintaining 9.5 V/µs negative slew rate at 5 V supply. Its input stage operates down to ground, eliminating level-shifting requirements in single-supply sensor front-ends.
It features internal ESD protection (±2 kV HBM), specified CMRR of 74 dB (min) over full temperature range, and PSRR of 65 dB (min), making it suitable for noisy industrial environments where supply ripple rejection and common-mode interference suppression are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 9 MHz - Enables stable closed-loop operation up to ~1 MHz at unity gain, sufficient for anti-aliasing and reconstruction filters in 12-bit+ SAR ADC interfaces. |
| Supply Current per Channel | 730 µA - Supports ultra-low-power operation in always-on sensor nodes powered by Li-ion or coin cells without compromising bandwidth. |
| Input Common-Mode Range | GND to VDD − 1 V - Allows direct connection to ground-referenced transducers (e.g., bridge sensors, thermocouples with cold-junction compensation) without external biasing. |
| Rail-to-Rail Output Swing | Within 100 mV of rails (at 10 mA load) - Maximizes dynamic range in 3.3 V or 5 V systems, improving SNR in precision analog signal chains. |
| Operating Temperature Range | −40°C to 125°C - Qualified for under-hood automotive, industrial motor control, and outdoor IoT edge nodes requiring extended thermal reliability. |
| Equivalent Input Noise Voltage | 50 nV/√Hz @ 1 kHz - Low-noise performance supports high-resolution measurement of µV-level signals from strain gauges or RTDs. |
| Output Drive Capability | ±28 mA (sourcing/sinking at 5 V) - Directly drives 100 Ω loads or multiple logic inputs without external buffers in mixed-signal interface circuits. |
Pinout & Package
TSSOP-14 (PW) package: 5.05 mm × 4.75 mm × 1.1 mm body, 0.65 mm pitch, exposed pad optional (non-connected per TI documentation), moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel A; rail-to-rail capable, drives loads up to ±28 mA. |
| 2 | IN− A | Inverting input of Channel A; high-impedance node (1000 GΩ differential resistance) for feedback network connection. |
| 3 | IN+ A | Non-inverting input of Channel A; accepts common-mode voltages from GND to VDD − 1 V. |
| 4 | VDD | Positive supply rail; accepts 2.7 V to 5.5 V single supply; decoupling capacitor required at pin. |
| 5 | IN+ B | Non-inverting input of Channel B; electrically isolated from other channels; shares same VDD and GND references. |
| 6 | IN− B | Inverting input of Channel B; used for differential or inverting configurations independent of Channel A. |
| 7 | OUT B | Amplified output of Channel B; identical AC/DC specs to OUT A; no crosstalk specification provided in datasheet. |
| 8 | GND | Analog ground reference; must be low-impedance path to system ground; shared by all four channels. |
| 9 | OUT D | Amplified output of Channel D; pin 9 is output, not NC - confirmed by TLV2634 pinout diagram on page 11 of SLOS362A. |
| 10 | IN− D | Inverting input of Channel D; matches IN− A/B/C electrical characteristics (input bias current ≤ 200 pA). |
| 11 | IN+ D | Non-inverting input of Channel D; supports same VICR as other channels (GND to VDD − 1 V). |
| 12 | VDD | Redundant VDD connection - pin 12 is tied internally to pin 4; improves power delivery integrity in high-frequency layouts. |
| 13 | IN+ C | Non-inverting input of Channel C; enables independent configuration of fourth amplifier in quad layout. |
| 14 | IN− C | Inverting input of Channel C; fully functional; no NC or dummy pins in TLV2634 TSSOP-14 configuration. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range in 3.3 V systems: VOH ≥ 2.67 V and VOL ≤ 0.1 V at 1 mA load (VDD = 2.7 V), preserving ADC resolution. |
| Ground-sensing input range | Accepts input signals down to 0 V (GND), eliminating need for external bias resistors when amplifying outputs from grounded sensors like pressure bridges. |
| Ultralow quiescent current | 730 µA per channel enables continuous monitoring in battery-operated devices with >1-year runtime on a single CR2032 cell (typical). |
| High-speed, low-noise operation | 9 MHz GBW + 50 nV/√Hz noise allows clean amplification of fast, low-amplitude signals (e.g., piezoelectric sensor outputs) without added distortion. |
| Extended temperature qualification | Specified performance across −40°C to 125°C ensures stability in automotive engine control units and industrial PLC I/O modules without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2784IPW | Lower supply voltage (1.8–3.6 V), 8 MHz GBW, 650 µA/ch, higher input offset (4200 µV max) | Better suited for sub-2 V MCU interfaces but lacks 5 V compatibility and exhibits higher DC error | Select TLV2784IPW only when operating strictly below 3.3 V and DC accuracy is secondary to ultra-low voltage support. |
| OPA2343UA/2K5 | Higher supply current (850 µA/ch), 5.5 MHz GBW, wider VICR (−0.3 V to VDD + 0.3 V), lower noise (25 nV/√Hz) | Superior noise performance for audio or precision DC, but reduced bandwidth limits high-speed sensor use | Choose OPA2343UA/2K5 when ultra-low noise dominates design priority and 5.5 MHz GBW suffices for signal bandwidth. |
Compared with TLV2784IPW and OPA2343UA/2K5, the TLV2634IPWR uniquely balances 9 MHz bandwidth, 2.7–5.5 V operation, and ground-sensing input in a quad TSSOP-14 package-making it optimal for mixed-voltage industrial sensor hubs requiring both speed and single-supply simplicity.

FAQ
What is the maximum recommended supply voltage for TLV2634IPWR?
The absolute maximum supply voltage for TLV2634IPWR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operating above 5.5 V risks permanent damage and violates the device's qualified specifications. At 5.5 V, the TLV2634IPWR maintains full rail-to-rail output swing and 9 MHz gain-bandwidth product as specified in the SLOS362A datasheet.
Does TLV2634IPWR include a shutdown feature?
No, TLV2634IPWR does not include a shutdown function. It is the quad-channel, non-shutdown variant in the TLV263x family. The pinout contains no SHDN terminal - pins 1–14 are fully allocated to amplifier inputs, outputs, power, and ground. For shutdown capability, engineers should select TLV2635IPWR (quad with shutdown) instead.
What is the input offset voltage specification for TLV2634IPWR over temperature?
The TLV2634IPWR has a maximum input offset voltage of 5200 µV across the full −40°C to 125°C industrial temperature range, with a typical value of 4200 µV at 25°C. Its temperature coefficient is 3 µV/°C, meaning offset drift remains tightly bounded - critical for precision DC-coupled applications like weigh scales or temperature transmitters.
Can TLV2634IPWR drive capacitive loads directly?
TLV2634IPWR is stable for capacitive loads up to 100 pF without external compensation, as confirmed by phase margin ≥50° and gain margin ≥20 dB in the datasheet. For loads exceeding 100 pF (e.g., long PCB traces or ADC input capacitance), a small series resistor (10–50 Ω) between output and load is recommended to maintain stability and prevent peaking.
Is TLV2634IPWR RoHS compliant and lead-free?
Yes, TLV2634IPWR is RoHS compliant and features a NIPDAU (nickel-palladium-gold) lead finish. Per TI's Package Option Addendum, it carries MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH) and is qualified for peak reflow temperatures up to 260°C - meeting JEDEC J-STD-020 standards for lead-free assembly.
