Product details
Overview
TLV2762ID from Texas Instruments is a dual-channel, micropower, rail-to-rail input/output operational amplifier with shutdown, operating from 1.8 V to 3.6 V supply. It delivers 500 kHz bandwidth and 0.20 V/μs slew rate at only 20 μA per channel, with 550 μV input offset voltage and 10 nA shutdown current. It is designed for ultra-low-power sensor signal conditioning in battery-powered industrial and portable instrumentation.
For engineers reviewing the TLV2762ID datasheet, TLV2762ID pinout, TLV2762ID application, or TLV2762ID equivalent, this page provides verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative op-amps for low-voltage, low-quiescent-current designs requiring rail-to-rail I/O and shutdown control.
Technical Context
The TLV2762ID uses CMOS input stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing within 15–75 mV of rails at ±100 μA load. Its micropower design integrates ultralow input bias current (3 pA typ) and shutdown logic that reduces supply current to 10 nA per channel while maintaining high isolation (>60 dB crosstalk suppression).
It is characterized across −40°C to +85°C and specified for 1.8 V operation-enabling direct use with two AA/AAA cells (down to end-of-life 0.9 V per cell). The device supports single-supply configurations without level-shifting circuitry and maintains stable unity-gain performance with capacitive loads up to 10 pF, or up to 100 pF with optional nulling resistor.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports direct operation from two alkaline/NiMH cells, including end-of-life 1.8 V condition. |
| Quiescent Current (per channel) | 20 μA - enables multi-year battery life in always-on sensor front-ends with mega-ohm gain resistors. |
| Shutdown Current (per channel) | 10 nA - reduces system standby power by >2000×, critical for intermittent measurement applications. |
| Input Offset Voltage | 550 μV max - ensures <0.1% error in 0.5 V full-scale sensor outputs without trimming. |
| Unity-Gain Bandwidth | 500 kHz - sufficient for anti-aliasing filtering and DC-coupled signal chains up to ~100 kHz. |
| Slew Rate | 0.20 V/μs - supports 1 Vpp signals up to ~100 kHz without distortion in unity-gain buffer configuration. |
| Input Bias Current | 3 pA typ - allows use with high-impedance pH electrodes, photodiodes, and thermopiles without leakage-induced error. |
| Output Drive Capability | ±5 mA min - drives 10 kΩ loads to rail with <100 mV headroom, compatible with SAR ADC reference buffers. |
Pinout & Package
TLV2762ID is packaged in an 8-pin MSOP (DGK) with exposed thermal pad. This compact 3 mm × 3 mm footprint supports high-density PCB layouts in space-constrained portable equipment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives loads down to 10 kΩ with <75 mV saturation. |
| 2 | IN− A | Inverting input A - high-impedance CMOS node; sensitive to layout-induced leakage above 100 MΩ traces. |
| 3 | IN+ A | Non-inverting input A - accepts common-mode voltages from −0.2 V to VDD + 0.2 V, enabling true single-supply sensing. |
| 4 | GND | Analog ground reference - must connect directly to low-inductance ground plane; shared with all channels. |
| 5 | SHDN | Active-low shutdown control - pulls below 0.6 V to enter 10 nA shutdown; high-impedance when inactive. |
| 6 | VDD | Positive supply - decoupled with 0.1 μF ceramic + 6.8 μF tantalum; tolerates 4 V absolute max. |
| 7 | OUT B | Amplifier B output - independently controllable; identical AC/DC specs to OUT A. |
| 8 | IN− B | Inverting input B - electrically isolated from Channel A; supports dual-sensor differential pairs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8 V systems - no level-shifting required for ADC interfacing or sensor biasing. |
| 20 μA per channel supply current | Reduces total quiescent power to <50 μW per amplifier at 1.8 V - extends coin-cell lifetime beyond 10 years in sleep-dominated duty cycles. |
| 10 nA shutdown current | Allows deep-sleep modes in data loggers and IoT edge nodes without compromising wake-up latency (<5 μs turn-on time). |
| 3 pA typical input bias current | Permits direct connection to high-Z sources (e.g., glass pH electrodes, pyroelectric sensors) without significant offset drift. |
| −40°C to +85°C industrial temp range | Validated for deployment in uncontrolled environments - automotive cabin modules, industrial field transmitters, outdoor metering. |
| MSOP-8 (DGK) package with thermal pad | Provides 260°C reflow compatibility and 54.2°C/W junction-to-ambient thermal resistance - suitable for sealed enclosures without forced airflow. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, micropower, rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2452IDR | Higher supply current (23 μA vs. 20 μA), higher offset (20 μV vs. 550 μV), no shutdown pin. | Lacks shutdown functionality; better for always-on, higher-accuracy applications where 3 μA extra current is acceptable. | Select TLV2452IDR if shutdown is unnecessary and lower offset is prioritized over ultra-low standby power. |
| LPV821DRX | Lower supply current (650 nA), lower bandwidth (10 kHz), no shutdown, single-channel only. | Not pin-compatible; requires redesign for dual-channel needs; suited for ultra-long-life, low-bandwidth sensor nodes. | Select LPV821DRX only for single-ended, sub-10 kHz applications where 30× lower quiescent current justifies board redesign. |
Compared with TLV2762ID, TLV2452IDR offers tighter offset but forfeits shutdown capability and consumes 15% more active current, while LPV821DRX achieves nanowatt operation at the cost of bandwidth and channel count - making TLV2762ID the optimal balance for dual-channel, shutdown-enabled, 500 kHz-capable micropower designs.

FAQ
What is the maximum supply voltage for TLV2762ID?
The absolute maximum supply voltage for TLV2762ID is 4 V. Operation above 3.6 V is not recommended, as the device is specified for reliable performance only within the 1.8 V to 3.6 V range. Exceeding 4 V may cause permanent damage, per the Absolute Maximum Ratings table in the SLOS326F datasheet.
Does TLV2762ID support rail-to-rail input at 1.8 V supply?
Yes, TLV2762ID supports rail-to-rail input at 1.8 V supply, with a common-mode input voltage range of −0.2 V to VDD + 0.2 V. At 1.8 V, this means inputs can swing from −0.2 V to +2.0 V, enabling direct interface with sensors whose output exceeds the supply rail - a key advantage in single-supply, low-voltage systems.
How fast does TLV2762ID wake up from shutdown mode?
TLV2762ID has a typical amplifier turn-on time (ton) of 5 μs, defined as the interval between SHDN rising above threshold and supply current reaching half its final value. This fast wake-up supports burst-mode sensing in energy-harvesting and duty-cycled IoT applications without sacrificing responsiveness.
Can TLV2762ID drive a 10 kΩ load to the rails?
Yes, TLV2762ID can drive a 10 kΩ load to within 75 mV of the positive rail and 30 mV of the negative rail at 1.8 V supply (per electrical characteristics tables). This rail-to-rail output capability ensures full utilization of ADC input ranges and eliminates need for external level-shifting circuitry in low-voltage systems.
Is TLV2762ID qualified for industrial temperature range?
Yes, TLV2762ID is rated for −40°C to +85°C operation (I-suffix grade), with full electrical specifications guaranteed across this range. It is validated for use in industrial automation, remote monitoring, and outdoor metering applications where ambient temperatures exceed commercial-grade limits.
