Product details
Overview
TLV2634ID 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, featuring 9 MHz gain-bandwidth product, 730 µA per channel supply current, and −40°C to 125°C industrial temperature range. It delivers ultralow power with ground-sensing input (VICR = GND to VDD−1 V) and supports high-resolution data converter interfacing in battery-powered instrumentation.
For engineers reviewing the TLV2634ID datasheet, TLV2634ID pinout, TLV2634ID application, or TLV2634ID equivalent, this page provides verified package mapping (SOIC-14), confirmed rail-to-rail output swing, validated shutdown behavior (IDD(SHDN) = 4 µA/channel), and real-world use cases in precision analog front-ends and Li-ion powered sensor signal conditioning.
Technical Context
The TLV2634ID implements a CMOS input stage enabling picoampere-level input bias current (1–100 pA) and rail-to-rail output swing within 100 mV of each rail at 10 mA load. Its 9 MHz GBW and 9.5 V/µs negative slew rate support unity-gain-stable operation into capacitive loads up to 50 pF without external compensation.
Designed for single-supply systems, it accepts common-mode inputs down to ground and operates across the full 2.7–5.5 V range-enabling direct interface with MSP430 microcontrollers and 1-cell Li-ion batteries. Shutdown control is provided via dedicated SHDN pins (pins 6 and 13), reducing quiescent current to 4 µA per channel.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 9 MHz - enables stable unity-gain buffer or 10× gain amplification up to 900 kHz. |
| Supply Current per Channel | 730 µA - supports always-on sensor signal conditioning with sub-3-mA total quad-channel draw at 5 V. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at 10 mA - preserves dynamic range when driving ADCs or low-voltage logic interfaces. |
| Input Common-Mode Range | GND to VDD−1 V - allows direct connection to ground-referenced transducers and single-ended sensors. |
| Shutdown Supply Current | 4 µA per channel - reduces system standby power by >99% versus active mode, critical for battery longevity. |
| Operating Temperature Range | −40°C to 125°C - qualified for under-hood automotive, industrial motor control, and outdoor IoT node deployment. |
| Equivalent Input Noise Voltage | 50 nV/√Hz at 1 kHz - suitable for low-level signal amplification in precision weigh scales and medical ECG front-ends. |
Pinout & Package
TLV2634ID is housed in a 14-pin SOIC (D) package with 1.27 mm pitch, 8.65 mm × 3.91 mm body, and exposed thermal pad not present. Pin 1 is located at the top-left corner adjacent to the index notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | OUT (Channel 1–4 outputs) | Amplified buffered outputs capable of sourcing/sinking ±28 mA at 5 V; rail-to-rail swing ensures full utilization of ADC input range. |
| 2, 6, 10, 13 | IN− (Inverting inputs) | Differential input terminals accepting signals up to VDD−1 V; high CMRR (≥67 dB) rejects noise in noisy industrial environments. |
| 3, 7, 11, 14 | IN+ (Non-inverting inputs) | High-impedance CMOS inputs (1–100 pA bias) enable direct connection to high-Z sources like thermocouples or piezoelectric sensors. |
| 4 | GND | Analog ground reference shared across all four channels; requires low-impedance PCB plane for noise immunity. |
| 8 | VDD | Single positive supply input (2.7–5.5 V); PSRR ≥65 dB minimizes ripple coupling into amplified signals. |
| 6, 13 | SHDN | Active-low shutdown control per pair (Ch1/Ch2 and Ch3/Ch4); drives IDD to 4 µA/channel when pulled ≤0.4 V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full-scale output voltage headroom into 2-kΩ loads, maximizing SNR in 12-bit+ SAR ADC interfaces. |
| Ground-sensing input range | Enables direct DC-coupled connection to 0-V referenced sensors (e.g., strain gauges, RTDs) without level-shifting circuitry. |
| Ultralow shutdown current | 4 µA per channel allows independent channel disable in multi-sensor nodes, extending battery life beyond 10 years in sleep-dominated duty cycles. |
| 9-MHz bandwidth at 730-µA/ch | Provides 10× higher speed-per-power than legacy micropower op-amps, enabling real-time filtering in portable diagnostic equipment. |
| Industrial temperature qualification | Guaranteed performance from −40°C to 125°C eliminates derating calculations for automotive cabin modules and factory-floor PLC I/O. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2624IDR | Higher 11 MHz GBW but 750 µA/ch supply current; input range starts at 1 V above ground (not ground-sensing). | Less suitable for ground-referenced sensor interfaces; better for higher-speed closed-loop control where VICR > 1 V is acceptable. | Select TLV2624IDR only if bandwidth >9 MHz is required and input signals never approach ground potential. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C offset drift), 350 µA/ch, but only 350 kHz GBW and no shutdown function. | Superior DC accuracy for long-term sensor calibration stability, but insufficient bandwidth for dynamic signal acquisition above 10 kHz. | Choose OPA2333PWR when ultra-low offset drift dominates over speed and power-down capability in precision weighing or environmental monitoring. |
Compared with TLV2634ID, TLV2624IDR trades ground-sensing input for higher bandwidth, while OPA2333PWR sacrifices speed and shutdown for near-zero drift-making TLV2634ID the optimal balance of rail-to-rail operation, low power, and industrial temperature robustness in mixed-signal sensor nodes.

FAQ
What is the maximum recommended supply voltage for TLV2634ID?
The absolute maximum supply voltage for TLV2634ID is 6 V, but the recommended operating range is strictly 2.7 V to 5.5 V. Exceeding 5.5 V risks permanent damage and invalidates parametric guarantees-even brief transients above this limit degrade long-term reliability. TI specifies 5.5 V as the upper bound for guaranteed performance across −40°C to 125°C.
Does TLV2634ID support true rail-to-rail input operation?
No, TLV2634ID does not support rail-to-rail input. Its input common-mode voltage range is specified as GND to VDD−1 V. While it accepts signals down to ground (enabling direct connection to ground-referenced sensors), it cannot handle inputs within 1 V of the positive rail. This differs from rail-to-rail input op-amps that accept VICR from GND to VDD.
How many independent shutdown controls does TLV2634ID provide?
TLV2634ID provides two independent shutdown controls: pin 6 disables channels 1 and 2, while pin 13 disables channels 3 and 4. Each SHDN pin is active-low and draws negligible current when asserted. This dual-control architecture allows selective power gating-for example, keeping pressure-sensing channels active while disabling ambient light monitoring channels in a multi-sensor node.
What is the typical output current capability of TLV2634ID per channel?
TLV2634ID delivers ±28 mA per channel at VDD = 5 V with VO within 0.5 V of either rail. At VDD = 2.7 V, output current is ±14 mA under the same condition. These values are measured with sourcing/sinking into resistive loads and represent the maximum linear output drive before clipping-critical for driving ADC reference buffers or low-impedance filters without external gain stages.
Is TLV2634ID pin-compatible with other TLV263x variants in SOIC-14?
Yes, TLV2634ID shares identical pinout and footprint with TLV2634IN (DIP-14) and TLV2634IPW (TSSOP-14) in the same functional variant. All TLV2634x quad-no-shutdown devices use the same SOIC-14 pin assignment shown in the datasheet Figure "TLV2634 D, N, OR PW PACKAGE", ensuring drop-in replacement across package types without PCB redesign.
