Product details
Overview
TLV2633IDGSR 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 systems. It operates from 2.7 V to 5.5 V, delivers 9 MHz gain-bandwidth, draws only 730 µA per channel, and supports industrial temperature range (−40°C to 125°C). It interfaces directly with ground-referenced sensors and ADCs in battery-powered data acquisition.
For engineers reviewing the TLV2633IDGSR datasheet, TLV2633IDGSR pinout, TLV2633IDGSR application, or TLV2633IDGSR equivalent, key selection criteria include its rail-to-rail output swing, ultralow 4 µA shutdown current, 9 MHz GBW at 730 µA, input common-mode range extending to GND, and MSOP-10 packaging for space-constrained designs.
Technical Context
The TLV2633IDGSR integrates two independent op-amps with individual shutdown pins (pins 5 and 10), enabling selective channel power gating. Its input stage includes ground-sensing capability (VICR = GND to VDD − 1 V), and output stage delivers rail-to-rail swing with ±28 mA drive capability.
It features a unity-gain-stable architecture with 9 MHz gain-bandwidth product, 9.5 V/µs negative slew rate (at VDD = 5 V), and 50 nV/√Hz input voltage noise - optimized for high-resolution SAR ADC drivers and low-distortion signal chains where supply current and dynamic performance must coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - compatible with Li-ion cells and MSP430 microcontrollers without level-shifting. |
| 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-channel operation under 1.5 mA total, critical for always-on sensor front-ends. |
| Shutdown Current per Channel | 4 µA - reduces system standby power by >99% versus active mode, enabling long battery life in intermittent sensing. |
| Input Common-Mode Range | GND to VDD − 1 V - accepts 0 V input signals directly, eliminating need for biasing networks in ground-referenced transducer interfaces. |
| Output Drive Capability | ±28 mA - drives 2 kΩ loads to rail while maintaining linearity, suitable for driving ADC reference buffers or small capacitive loads. |
| Input Voltage Noise | 50 nV/√Hz at 1 kHz - preserves SNR in 16-bit+ data converter interfaces where noise contribution must be <1 LSB. |
Pinout & Package
TLV2633IDGSR is housed in a 10-pin MSOP (DGS) package (4.0 mm × 3.0 mm, 0.5 mm pitch), thermally enhanced with exposed pad for improved power dissipation. Pin 1 is marked via laser etch or mold index; pin 1 location confirmed per JEDEC MO-187.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier channel - rail-to-rail capable, drives external load or next-stage input. |
| 2 | 1IN− | Inverting input of first channel - used for feedback configuration (e.g., inverting amplifier, transimpedance). |
| 3 | 1IN+ | Non-inverting input of first channel - accepts ground-referenced sensor signals without level shift. |
| 4 | GND | Analog ground reference - shared return path for both channels and shutdown logic; requires low-impedance PCB connection. |
| 5 | 1SHDN | Active-low shutdown control for Channel 1 - pulls below 0.4 V to disable amplifier; high-Z when inactive. |
| 6 | VDD | Positive supply rail - powers both amplifiers and internal bias circuitry; decoupling capacitor required at pin. |
| 7 | 2IN+ | Non-inverting input of second channel - independently configurable for differential or single-ended inputs. |
| 8 | 2IN− | Inverting input of second channel - supports matched feedback networks for precision instrumentation topologies. |
| 9 | 2OUT | Output of second amplifier channel - fully independent; can be used for reference buffering or signal conditioning. |
| 10 | 2SHDN | Active-low shutdown control for Channel 2 - enables independent power management per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of rails at 10 mA load, maximizing dynamic range for 3.3 V or 5 V ADCs. |
| Ground-sensing input range | Accepts 0 V common-mode input, eliminating DC bias resistors in thermocouple or bridge sensor interfaces. |
| Ultralow shutdown current | 4 µA per channel ensures <1 µA total quiescent current when both channels disabled - ideal for wake-on-event architectures. |
| Industrial temperature rating | Specified from −40°C to 125°C, supporting deployment in automotive engine control modules and industrial motor drives. |
| Low input voltage noise | 50 nV/√Hz at 1 kHz enables accurate amplification of µV-level signals from strain gauges or RTDs without added filtering. |
| MSOP-10 thermal performance | ΘJA = 259.7°C/W enables 97 mW power dissipation at TA = 125°C - sufficient for dual-channel operation at full spec. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2632IDGKR | Dual op-amp, same family, no shutdown function; 750 µA/ch supply current; identical GBW (9 MHz) and noise (50 nV/√Hz). | Lacks per-channel shutdown - unsuitable for duty-cycled sensor nodes requiring ultra-low standby power. | Select TLV2632IDGKR only if shutdown is unnecessary and cost minimization is prioritized over power flexibility. |
| OPA2343UA | Higher supply current (850 µA/ch), lower GBW (5.5 MHz), wider VICR (−0.3 V to VDD+0.3 V), but no shutdown. | Better input overvoltage tolerance; not rated for 125°C operation - limited to commercial/industrial ambient ≤85°C. | Choose OPA2343UA only when input fault protection beyond rail is required and extended temperature operation is not needed. |
Compared with TLV2633IDGSR, TLV2632IDGKR offers identical performance without shutdown overhead, while OPA2343UA trades bandwidth and temperature range for enhanced input voltage range - making TLV2633IDGSR the sole option combining shutdown, 125°C rating, and 9 MHz GBW in MSOP-10.

FAQ
What is the maximum operating junction temperature for TLV2633IDGSR?
The absolute maximum junction temperature for TLV2633IDGSR is 150°C. Under recommended operating conditions (TA = −40°C to 125°C), the device maintains full electrical specifications. Thermal design must ensure θJA = 259.7°C/W and proper PCB copper area under the exposed pad to avoid exceeding TJ(max) during continuous 28 mA output loading.
Does TLV2633IDGSR support split-supply operation?
Yes, TLV2633IDGSR supports split-supply operation with ±1.35 V to ±2.75 V rails, as specified in the recommended operating conditions. However, its rail-to-rail output and ground-inclusive input range are optimized for single-supply use; split-supply configurations require careful biasing of IN+ and IN− to maintain common-mode compliance.
What is the typical turn-on time for TLV2633IDGSR after asserting SHDN high?
The typical amplifier turn-on time for TLV2633IDGSR is 1.5 µs (at VDD = 5 V, RL = 2 kΩ, CL = 10 pF), defined as the interval between SHDN rising above 2 V and supply current reaching 50% of its active value. This fast enable time supports burst-mode sensing in energy-harvesting systems.
Can TLV2633IDGSR drive a 1000 pF capacitive load stably?
No - TLV2633IDGSR is unity-gain stable only for capacitive loads ≤100 pF, as confirmed by phase margin testing (≥50° at CL = 10 pF). Driving 1000 pF directly causes severe peaking and potential oscillation; a series resistor (≥100 Ω) or isolation buffer is required for larger capacitive loads.
Is the exposed thermal pad on TLV2633IDGSR electrically connected internally?
No - the exposed pad on the TLV2633IDGSR MSOP-10 package is not electrically connected to any internal node. It is intended solely for thermal conduction and must be soldered to a large PCB copper pour tied to GND for optimal thermal performance and mechanical reliability.
