Product details
Overview
TLV2632IP 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 product with only 730 µA per channel supply current, supports −40°C to 125°C industrial temperature range, and features ground-sensing input (VICR = GND to VDD−1 V). It is used in high-resolution data acquisition front-ends interfacing directly to ground-referenced sensors.
For engineers reviewing the TLV2632IP datasheet, TLV2632IP pinout, TLV2632IP application, or TLV2632IP equivalent, key selection criteria include its rail-to-rail output swing, ultralow quiescent current, extended temperature rating, and compatibility with Li-ion powered systems and MSP430 microcontrollers.
Technical Context
The TLV2632IP operates as a voltage-feedback op-amp with unity-gain stable architecture, achieving 9 MHz GBW while maintaining 9.5 V/µs negative slew rate at 5 V supply. Its input stage uses complementary input pairs enabling rail-to-rail common-mode input range down to ground.
It integrates no internal shutdown circuitry (as confirmed by absence of SHDN pin in DIP-8 pinout), distinguishing it from TLV2630/3/5 variants. The device exhibits 67–74 dB CMRR over full temperature range and 50 nV/√Hz input voltage noise at 1 kHz - critical for precision signal conditioning in low-noise sensor interfaces.
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 without phase margin degradation. |
| Supply Current per Channel | 730 µA - allows battery-powered designs with multi-day runtime using coin cells or Li-ion sources. |
| Input Common-Mode Range | GND to VDD−1 V - permits direct connection to ground-referenced transducers and single-ended ADC drivers. |
| Rail-to-Rail Output Swing | Within 100 mV of rails (at 1 mA load) - maximizes dynamic range in 3.3 V or 5 V systems without level-shifting. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive, industrial motor control, and outdoor instrumentation. |
| Input Voltage Noise | 50 nV/√Hz at 1 kHz - supports 16-bit+ SAR ADC front-end performance without significant SNR degradation. |
| Output Drive Capability | ±28 mA at 5 V - drives 2 kΩ loads with <0.1% THD+N, suitable for active filters and DAC buffers. |
Pinout & Package
The TLV2632IP is housed in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and through-hole mounting. This package provides mechanical robustness and thermal stability for prototyping and legacy PCB designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance differential input node; connects to feedback network in inverting configurations. |
| 2 | Non-Inverting Input (Channel 1) | Accepts ground-referenced or single-ended signals; common-mode range includes GND. |
| 3 | Output (Channel 1) | Capable of sourcing/sinking ±28 mA; rail-to-rail swing enables full utilization of ADC reference voltage. |
| 4 | Ground | Common return path for both channels; must be low-impedance to minimize PSRR degradation. |
| 5 | Non-Inverting Input (Channel 2) | Independent input for second amplifier; shares same GND and VDD references. |
| 6 | Inverting Input (Channel 2) | Used for differential-to-single-ended conversion or independent signal conditioning path. |
| 7 | Output (Channel 2) | Electrically isolated output stage; supports dual-sensor readout or stereo audio pre-amplification. |
| 8 | Positive Supply (VDD) | Accepts 2.7–5.5 V single supply; PSRR of 65–90 dB suppresses supply ripple in noisy environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers >98% of supply rail-to-rail voltage range at 1 mA load, preserving signal fidelity in low-voltage systems. |

| Ultralow power consumption | 730 µA per channel allows integration into always-on monitoring nodes with multi-year battery life. |
| Wide supply voltage range | 2.7 V to 5.5 V operation supports both Li-ion (3.0–4.2 V) and 5 V legacy systems without regulator overhead. |
| High-speed precision | 9 MHz GBW + 50 nV/√Hz noise enables accurate amplification of fast, low-amplitude signals in data converter 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 |
|---|---|---|---|
| TLV2632ID | SOIC-8 package; identical electrical specs; RoHS-compliant, surface-mount variant. | Preferred for automated assembly and space-constrained PCBs; requires reflow-compatible layout. | Select TLV2632ID for volume production with pick-and-place manufacturing; TLV2632IP remains optimal for breadboarding and repair. |
| OPA2343UA | 5.5 V max supply; 850 µA/channel; 5.5 MHz GBW; higher input bias current (1 pA vs 1–50 pA). | Better suited for general-purpose buffering where bandwidth demand is ≤5 MHz and noise is less critical. | Choose OPA2343UA when cost sensitivity outweighs bandwidth/noise requirements; not recommended for high-fidelity sensor front-ends. |
Compared with TLV2632ID and OPA2343UA, the TLV2632IP offers superior bandwidth-to-power ratio (9 MHz @ 730 µA) and lower input voltage noise, making it the preferred choice for precision, low-power dual-channel amplification where through-hole mounting is acceptable.

FAQ
What is the maximum supply voltage for TLV2632IP?
The absolute maximum supply voltage for TLV2632IP 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 the device's specified conditions. At 5.5 V, the amplifier maintains full rail-to-rail output swing and 9 MHz gain-bandwidth product, as verified in the SLOS362A datasheet Section 3 (Absolute Maximum Ratings) and Section 5 (Recommended Operating Conditions).
Does TLV2632IP include a shutdown feature?
No, TLV2632IP does not include a shutdown feature. It is the dual-channel, non-shutdown variant in the TLV263x family. Pinout diagrams confirm no SHDN terminal; only TLV2630 (single with shutdown), TLV2633 (dual with shutdown), and TLV2635 (quad with shutdown) contain shutdown functionality. This is explicitly stated in the "PACKAGE/ORDERING INFORMATION" table and "TLV263x PACKAGE PINOUTS" section of the SLOS362A datasheet.
What is the input common-mode voltage range of TLV2632IP?
The input common-mode voltage range of TLV2632IP is GND to VDD−1 V, as specified in both the "FEATURES" summary and "recommended operating conditions" table of the SLOS362A datasheet. This ground-inclusive range enables direct connection to 0 V referenced sources such as bridge sensors and thermocouples without external biasing networks, and is validated across the full −40°C to 125°C temperature range.
Can TLV2632IP drive a 2 kΩ load with rail-to-rail output?
Yes, TLV2632IP can drive a 2 kΩ load with rail-to-rail output swing. At VDD = 5 V and IO = ±1 mA, VOH ≥ 4.9 V and VOL ≤ 0.08 V (typical), achieving >98% of full rail span. This is confirmed in the "output characteristics" table (Page 4) of SLOS362A, where VOH/VOL values are measured under RL = 2 kΩ, ensuring compatibility with standard ADC reference buffers and active filter stages.
Is TLV2632IP compatible with lithium-ion battery-powered systems?
Yes, TLV2632IP is fully compatible with lithium-ion battery-powered systems. Its 2.7 V minimum supply voltage aligns with the discharge endpoint of Li-ion cells (≈2.7–3.0 V), and its 5.5 V maximum accommodates full charge voltage (4.2 V) with margin. The 730 µA per channel supply current enables multi-day operation on typical 500 mAh batteries, as documented in the "FEATURES" and "power supply" sections of the SLOS362A datasheet.
