Product details
Overview
TLV2633ID from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier with shutdown control, designed for precision analog signal conditioning in single-supply industrial systems. It delivers 9 MHz gain-bandwidth, 730 µA per channel supply current, rail-to-rail output swing, ground-sensing input (VICR = GND to VDD−1 V), and operates across −40°C to +125°C at 2.7 V to 5.5 V supply. It is used in high-resolution data acquisition front-ends interfacing with SAR ADCs.
For engineers reviewing the TLV2633ID datasheet, TLV2633ID pinout, TLV2633ID application, or TLV2633ID equivalent, key selection criteria include shutdown current (4 µA/channel), input offset voltage (max 4500 µV over temperature), output drive capability (±28 mA), CMRR (min 67 dB), and SOIC-14 package compatibility with legacy layout footprints.
Technical Context
The TLV2633ID implements a dual-channel architecture with independent shutdown control per amplifier, enabling selective power gating in multi-stage signal chains. Its input stage supports common-mode voltages down to ground while maintaining rail-to-rail output swing - critical for low-voltage, ground-referenced sensor interfaces.
It features a unity-gain stable design with 9 MHz GBW and 9.5 V/µs negative slew rate at 5 V supply, optimized for driving capacitive loads up to 10 pF without oscillation. Shutdown mode reduces supply current to 4 µA/channel with 200 ns turnoff time and 1.5 µs turnon time at 5 V, supporting fast power cycling in battery-sensitive applications.
Key Specifications

|---|---|
| Gain-bandwidth product | 9 MHz - enables stable unity-gain buffer operation up to ~9 MHz or closed-loop gain of 10 at ~900 kHz. |
| Supply current per channel | 730 µA - allows dual op-amp operation from microcontroller LDO rails without excessive quiescent load. |
| Input common-mode range | GND to VDD−1 V - permits direct connection to ground-referenced transducer outputs (e.g., bridge sensors). |
| Rail-to-rail output swing | Within 100 mV of rails at 10 mA load - preserves dynamic range in 3.3 V or 5 V systems driving ADC reference buffers. |
| Shutdown supply current | 4 µA per channel - reduces system standby power by >99% versus active mode, suitable for duty-cycled sensing nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp with shutdown applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2633IDGS | Same silicon die, but in 10-pin MSOP (DGS) package - smaller footprint (3.0 × 3.0 mm), higher thermal resistance (ΘJA = 259.7°C/W). | Preferred for space-constrained PCBs where thermal margin allows; requires re-layout due to different pinout and pad geometry. | Select TLV2633IDGS when board area is critical and thermal derating is acceptable; use TLV2633ID for legacy SOIC compatibility and easier thermal management. |
| OPA2343UA | Lower GBW (5.5 MHz), higher supply current (850 µA/ch), wider VICR (−0.3 V to VDD+0.3 V), no shutdown function. | Suitable for non-power-gated designs requiring extended input range beyond rail; lacks independent channel shutdown. | Choose OPA2343UA only if extended input voltage range is mandatory and shutdown is unnecessary; TLV2633ID provides superior power efficiency and channel-level control. |
Compared with TLV2633IDGS, the TLV2633ID offers lower thermal resistance and proven manufacturability in SOIC-14, while OPA2343UA trades shutdown capability and power savings for broader input voltage tolerance - making TLV2633ID optimal for battery-operated, thermally robust dual-amplifier signal chains.

FAQ
What is the maximum recommended supply voltage for TLV2633ID?
The absolute maximum supply voltage for TLV2633ID 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 TI's specified conditions; sustained use at 6 V is not supported. Designers should maintain VDD ≤ 5.5 V with appropriate decoupling to ensure reliability across −40°C to +125°C.
Does TLV2633ID support true rail-to-rail input operation?
No, TLV2633ID does not support rail-to-rail input. Its input common-mode voltage range is specified as GND to VDD−1 V - meaning the maximum input voltage is 1 V below the positive rail. It does provide rail-to-rail *output* swing, but input signals must stay ≥1 V below VDD to avoid phase reversal or increased offset error. This is confirmed in the "Recommended Operating Conditions" table of the SLOS362A datasheet.
Can TLV2633ID drive a 10 kΩ load while maintaining rail-to-rail output?
Yes, TLV2633ID maintains rail-to-rail output swing into 10 kΩ loads across its full operating range. The datasheet specifies VOH ≥ VDD−0.1 V and VOL ≤ 0.15 V at 1 mA load (which corresponds to 10 kΩ at 1 V drop), and these values degrade only marginally at higher currents. At 10 kΩ, output swing remains within 100 mV of both rails at 25°C and full temperature range, preserving dynamic range for precision ADC interfacing.
What is the typical turnon time for TLV2633ID when exiting shutdown mode?
The typical amplifier turnon time for TLV2633ID is 1.5 µs at VDD = 5 V with RL = 2 kΩ and CL = 10 pF, as measured from SHDN rising edge to supply current reaching 50% of final value. At VDD = 2.7 V, turnon time increases to 4.5 µs. These values are specified in the "Shutdown Characteristics" table and enable deterministic timing in sampled-data systems requiring synchronized amplifier activation.
Is TLV2633ID pin-compatible with other TLV263x variants in SOIC-14 packages?
No, TLV2633ID is not pin-compatible with TLV2634ID (quad, no shutdown) or TLV2635ID (quad with shared shutdown) in SOIC-14 packages. While all share the same 14-pin SOIC outline, the pin functions differ significantly - e.g., TLV2633ID dedicates Pins 6 and 13 to independent shutdown controls, whereas TLV2634ID uses those pins as NC or channel inputs. Layout reuse is not possible without schematic and footprint revision.
