Product details
Overview
TLV2634IDR from Texas Instruments is a quad 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, −40°C to 125°C industrial temperature range, and ground-sensing input voltage range (VICR = GND to VDD−1 V). It enables high-resolution data acquisition in battery-powered instrumentation and sensor signal conditioning.
For engineers reviewing the TLV2634IDR datasheet, TLV2634IDR pinout, TLV2634IDR application, or TLV2634IDR equivalent, key selection criteria include rail-to-rail output swing, ultralow quiescent current at 2.7-V operation, guaranteed performance over extended temperature, and SOIC-14 package compatibility with legacy analog layouts.
Technical Context
The TLV2634IDR integrates four independent amplifiers on a single die with fully differential input stages supporting common-mode inputs down to ground-enabling direct interfacing with unipolar sensors and ADC reference rails. Its 9 MHz GBW and 9.5 V/µs slew rate support unity-gain-stable operation in active filters and buffer stages driving 2-kΩ loads.
Each channel operates independently with no internal shutdown control; the TLV2634IDR variant lacks enable/shutdown functionality (unlike TLV2635), simplifying biasing but excluding power-gating capability. Input offset voltage remains ≤5200 µV across −40°C to 125°C, and PSRR exceeds 65 dB over full supply range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 9 MHz - supports stable unity-gain buffers and 2nd-order anti-aliasing filters up to ~1.4 MHz. |
| Supply Current per Channel | 730 µA - enables 4-channel analog front-end operation below 3 mA total at 5 V, suitable for Li-ion portable systems. |
| Input Voltage Range | GND to VDD−1 V - allows direct connection to ground-referenced transducers without level-shifting circuitry. |
| Rail-to-Rail Output Swing | Within 100 mV of rails at 10 mA load - preserves dynamic range when driving SAR ADCs with 2.5-V or 5-V references. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive sensors and industrial motor control feedback loops. |
| Equivalent Input Noise | 50 nV/√Hz at 1 kHz - maintains SNR > 86 dB for 16-bit ADC interfaces with 10-kHz bandwidth. |
| Common-Mode Rejection | ≥67 dB over full temperature - suppresses supply ripple and shared-ground interference in multi-channel systems. |
Pinout & Package
TLV2634IDR is housed in a 14-pin SOIC (D) package with 1.27-mm pitch, 8.65-mm body length, and 3.9-mm width. The package supports standard reflow profiles (MSL Level-1, 260°C peak) and features exposed pad-free construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 12 | IN− (Inverting Input) | Differential input node for channels 1–4; accepts signals from GND to VDD−1 V. |
| 2, 4, 6, 13 | IN+ (Non-inverting Input) | Differential input node for channels 1–4; same VICR as IN−, enabling true ground-referenced sensing. |
| 7, 8, 10, 14 | OUT (Output) | Rail-to-rail output capable of sourcing/sinking ±28 mA at 5 V, driving 2-kΩ loads to within 100 mV of rails. |
| 9 | VDD | Positive supply rail for all four amplifiers; accepts 2.7 V to 5.5 V with 6-V absolute max rating. |
| 11 | GND | Analog ground reference shared by all channels; requires low-impedance PCB connection to minimize crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers full-scale swing to within 100 mV of supply rails at 10-mA load, maximizing ADC utilization in 3.3-V systems. |
| Ground-sensing input | Accepts common-mode voltages down to GND, eliminating need for input biasing resistors in single-supply sensor interfaces. |
| Low-power precision | 730 µA/channel quiescent current with 9-MHz GBW enables battery-operated 16-bit data loggers with >100-hour runtime. |
| Extended temperature range | Guaranteed operation from −40°C to 125°C supports deployment in automotive engine control units and industrial PLC I/O modules. |
| High PSRR & CMRR | ≥65 dB supply rejection and ≥67 dB common-mode rejection maintain accuracy in noisy 12-V automotive or 24-V factory-floor environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2784IDR | Lower supply voltage (1.8–3.6 V), 650 µA/channel, 8-MHz GBW, input range extends to VDD+0.2 V. | Better suited for ultra-low-voltage microcontroller interfaces (e.g., MSP430 FRAM series) but not rated above 3.6 V. | Select TLV2784IDR only if system supply is strictly ≤3.6 V and higher CMRR (>80 dB) is required. |
| OPA4343UA | Higher GBW (44 MHz), 8-mA/channel supply current, rail-to-rail I/O, wider supply (2.7–5.5 V), lower noise (7 nV/√Hz). | Targeted at high-speed data acquisition (e.g., oscilloscope front-ends), not optimized for battery life. | Choose OPA4343UA when bandwidth >10 MHz or noise <10 nV/√Hz is mandatory; avoid for energy-constrained designs. |
Compared with TLV2784IDR, TLV2634IDR offers higher supply voltage tolerance and better high-temperature stability; compared with OPA4343UA, it reduces quiescent power by 91% at the cost of bandwidth and noise performance-making TLV2634IDR optimal for precision, low-power, wide-temperature industrial sensing.

FAQ
What is the maximum supply voltage for TLV2634IDR?
The absolute maximum supply voltage for TLV2634IDR is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operation beyond 5.5 V risks permanent damage and invalidates parametric guarantees. At 5.5 V, the device maintains full rail-to-rail output swing and specified GBW, making it compatible with nominal 5-V systems including those with minor ripple or transient overshoot.
Does TLV2634IDR include shutdown functionality?
No, TLV2634IDR does not include shutdown control. It is the quad-channel, non-shutdown variant of the TLV263x family. Shutdown capability is present only in TLV2635 (quad with shutdown) and TLV2633 (dual with shutdown). TLV2634IDR draws 730 µA per channel continuously when powered; system-level power gating must be implemented externally via VDD switching.
What is the input common-mode voltage range of TLV2634IDR?
The input common-mode voltage range of TLV2634IDR is GND to VDD−1 V across the full −40°C to 125°C temperature range. This ground-sensing capability allows direct interface with 0-V referenced sources such as thermistors, bridge sensors, and DAC outputs without level-shifting circuitry-reducing component count and error sources in precision measurement paths.
Can TLV2634IDR drive a 10-kΩ load with rail-to-rail output?
Yes, TLV2634IDR delivers rail-to-rail output swing into 10-kΩ loads across its full operating temperature range. Output voltage reaches within 10 mV of rails under light loading (≤1 mA), and remains within 100 mV at 10-mA loads. For 10-kΩ, the output typically settles within 20 mV of rails-fully preserving dynamic range for 12- to 16-bit ADC interfaces in 3.3-V or 5-V systems.
Is TLV2634IDR pin-compatible with other TLV263x variants in SOIC-14?
No, TLV2634IDR is not pin-compatible with TLV2635ID (quad with shutdown) in SOIC-14. TLV2635 adds dedicated shutdown pins (pins 8 and 15), altering the pinout. TLV2634IDR uses pins 7, 8, 10, and 14 as outputs, while TLV2635 reassigns pin 8 as 1/2SHDN and pin 15 as 3/4SHDN. Board layout must be verified against the specific variant's pin diagram before substitution.
