Product details
Overview
TLV2632ID from Texas Instruments is a dual-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) across −40°C to 125°C. It is used in high-resolution data acquisition front-ends interfacing with SAR ADCs in battery-powered industrial sensors.
For engineers reviewing the TLV2632ID datasheet, TLV2632ID pinout, TLV2632ID application, or TLV2632ID equivalent, key selection criteria include its rail-to-rail output swing at low supply voltage, ultralow quiescent current in active mode, shutdown capability (IDD(SHDN) = 4 µA/channel), wide industrial temperature range, and SOIC-8 package compatibility with legacy layouts.
Technical Context
The TLV2632ID implements a CMOS input stage enabling ground-referenced common-mode input operation and rail-to-rail output swing using complementary output transistors. Its 9 MHz gain-bandwidth product is achieved with only 730 µA per channel, supporting unity-gain stable operation into capacitive loads up to 10 pF without external compensation.
It features an integrated shutdown control pin (SHDN) that reduces supply current to 4 µA per channel while maintaining fast turn-on (1.5 µs at VDD = 5 V) and turn-off (200 ns) times. Input offset voltage is specified at 4500 µV maximum over full temperature range, with 3 µV/°C drift coefficient.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 9 MHz - enables stable unity-gain buffer or 2× gain configuration up to ~4.5 MHz signal bandwidth |
| Supply current per channel | 730 µA - supports >10-year battery life in always-on sensor nodes powered by coin cells or Li-ion |
| Input common-mode range | GND to VDD − 1 V - allows direct interface to ground-referenced transducers and microcontroller ADC references |
| Rail-to-rail output swing | Within 100 mV of rails at 10 mA load - maximizes dynamic range when driving 12-bit+ SAR ADCs |
| Shutdown supply current | 4 µA per channel - reduces system standby power to sub-µW level when paired with external enable logic |
| Operating temperature | −40°C to 125°C - qualified for under-hood automotive, motor drive feedback, and industrial PLC environments |
| Input offset voltage | 4500 µV max - limits DC error to <0.1% FSR in 12-bit systems with 3.3 V reference |
Pinout & Package
TLV2632ID is supplied in an 8-pin SOIC (D) package, 3.91 mm × 4.9 mm body, 1.75 mm height, with standard 1.27 mm pitch. Pin 1 is marked by a beveled corner or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplified output of Channel A - drives ADC input or analog multiplexer with rail-to-rail swing |
| 2 | IN− A | Inverting input of Channel A - accepts differential or single-ended feedback network |
| 3 | IN+ A | Non-inverting input of Channel A - connects directly to sensor output or reference divider |
| 4 | GND | Analog ground reference - must be low-impedance connection shared with ADC and reference IC |
| 5 | VDD | Positive supply rail - accepts 2.7–5.5 V; decoupling capacitor required within 5 mm of pin |
| 6 | IN+ B | Non-inverting input of Channel B - enables dual-sensor monitoring or signal conditioning + reference buffer |
| 7 | IN− B | Inverting input of Channel B - supports independent gain configuration per channel |
| 8 | OUT B | Amplified output of Channel B - provides second analog path without cross-talk (typical crosstalk −120 dB) |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 100 mV of VDD and GND at 10 mA load - preserves full ADC input range in 3.3 V systems |
| Ground-sensing input | Common-mode range includes GND - eliminates need for level-shifting circuitry with grounded thermocouples or strain gauges |
| Ultralow shutdown current | 4 µA per channel - enables microcontroller-controlled power gating without significant leakage penalty |
| Wide supply range | 2.7 V to 5.5 V - operates directly from single Li-ion cell (3.0–4.2 V) or regulated 3.3 V/5 V rails |
| Industrial temperature grade | −40°C to 125°C - meets AEC-Q100 stress test requirements for non-automotive engine bay applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2343IDR | Higher supply current (850 µA/ch), lower GBW (5.5 MHz), wider VICR (−0.3 V to VDD + 0.3 V) | Better for AC-coupled, rail-splitting designs; less suitable for true ground-referenced DC sensing | Select when extended input voltage range beyond rails is required and higher power is acceptable |
| TLV2622IDR | Higher GBW (11 MHz), slightly higher supply current (750 µA/ch), narrower VICR (1 V to VDD + 0.2 V) | Optimized for higher-speed closed-loop control; cannot interface directly to ground-referenced sources | Select when >9 MHz bandwidth is critical and input signals stay ≥1 V above GND |
Compared with OPA2343IDR and TLV2622IDR, TLV2632ID uniquely balances rail-to-rail output, ground-sensing input, and ultralow 730 µA/ch supply current-making it the only option among the three qualified for battery-powered, ground-referenced, precision DC signal chains operating across −40°C to 125°C.

FAQ
What is the maximum recommended supply voltage for TLV2632ID?
The absolute maximum supply voltage for TLV2632ID is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operation at 5.5 V is fully characterized and supported across −40°C to 125°C. Exceeding 5.5 V risks parametric degradation and reduced reliability, even if below the 6 V absolute maximum rating.
Does TLV2632ID support true rail-to-rail input operation?
No, TLV2632ID does not support rail-to-rail input. Its common-mode input voltage range is specified as GND to VDD − 1 V. This means the input can reach ground but cannot swing to the positive rail. However, it does provide rail-to-rail output swing, delivering voltages within 100 mV of both VDD and GND under 10 mA load.
How is the shutdown function implemented on TLV2632ID?
TLV2632ID does not include a dedicated shutdown pin. The part number TLV2632ID corresponds to the dual, no-shutdown variant (as confirmed in the PACKAGE/ORDERING INFORMATION table). Shutdown functionality is only available on TLV2633ID (dual with shutdown) and TLV2630ID/TLV2635ID (single/quad with shutdown). TLV2632ID remains always-active.
What is the typical input offset voltage of TLV2632ID at room temperature?
The typical input offset voltage of TLV2632ID at 25°C is 250 µV, with a maximum of 4500 µV over the full −40°C to 125°C temperature range. The temperature coefficient is 3 µV/°C, meaning offset drift contributes ≤375 µV over a 125°C span - critical for DC-coupled precision applications.
Which package variants are available for TLV2632ID?
TLV2632ID is offered in two package options: SOIC-8 (package code D, orderable as TLV2632IDR) and VSSOP-8 (package code DGK, orderable as TLV2632IDGKR). Both are RoHS-compliant, rated for −40°C to 125°C, and share identical electrical specifications. The VSSOP-8 (DGK) is 3.0 mm × 3.0 mm, while SOIC-8 (D) is 3.91 mm × 4.9 mm.
