Product details
Overview
TLV2762IP from Texas Instruments is a dual-channel, micropower, rail-to-rail input/output operational amplifier with shutdown control, designed for ultra-low-voltage operation (1.8 V to 3.6 V). 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 - ideal for battery-powered sensor signal conditioning in industrial temperature range (−40°C to 85°C).
For engineers reviewing the TLV2762IP datasheet, TLV2762IP pinout, TLV2762IP application, or TLV2762IP equivalent, key selection considerations include its dual-channel MSOP-8 package, 1.8 V minimum supply compatibility, rail-to-rail I/O swing, integrated shutdown functionality, and verified performance down to end-of-life 2-cell AA/AAA battery voltages.
Technical Context
The TLV2762IP employs CMOS input stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and ultralow input bias current (3 pA typical). Its micropower design integrates a dedicated SHDN pin that reduces supply current to 10 nA per channel when asserted low, with fast enable/disable timing (5 μs turn-on, 0.8 μs turn-off).
It operates across −40°C to 85°C with guaranteed specifications at 1.8 V, 2.4 V, and 3.6 V supply; output drive capability reaches ±5 mA at 1.8 V and ±10 mA at 2.4 V, while maintaining rail-to-rail output swing within 15–75 mV of rails under 100–500 μA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports single-cell LiFePO₄, two alkaline/AA/AAA, or NiMH/NiCd battery operation. |
| Supply Current (per channel) | 20 μA typical at 1.8 V - enables multi-year battery life in low-duty-cycle sensing applications. |
| Shutdown Current (per channel) | 10 nA typical - reduces system standby power by >2000× versus active mode. |
| Unity-Gain Bandwidth | 500 kHz - sufficient for precision DC-coupled amplification and low-frequency filtering up to ~100 kHz. |
| Input Offset Voltage | 550 μV max at 25°C - ensures <1 mV error in 12-bit ADC front-end designs with gain ≤10. |
| Slew Rate | 0.20 V/μs - supports clean step response for signals up to ~30 kHz full-power bandwidth. |
| Input Common-Mode Range | −0.2 V to VDD + 0.2 V - allows direct interfacing with 0 V-referenced sensors and single-supply DAC outputs. |
Pinout & Package
TLV2762IP is housed in an 8-pin plastic DIP (dual in-line package), with pinout identical to industry-standard dual op-amp DIP-8 footprint. This through-hole package provides mechanical robustness and ease of prototyping, and is compatible with standard PCB layouts used for legacy dual op-amps.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - rail-to-rail capable, drives loads ≥10 kΩ without significant swing loss. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (1000 GΩ), sensitive to PCB leakage. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts signals from −0.2 V to VDD + 0.2 V. |
| 4 | GND | Analog ground reference - must be connected to low-noise system ground plane. |
| 5 | SHDN | Active-low shutdown control - pulls to GND to disable both channels; floats or ties to VDD to enable. |
| 6 | VDD | Positive supply rail - decoupling capacitor (0.1 μF ceramic + 6.8 μF tantalum) required at pin. |
| 7 | 2OUT | Output of Channel 2 - independent output, fully rail-to-rail, no crosstalk in shutdown mode. |
| 8 | 2IN− | Inverting input of Channel 2 - electrically isolated from Channel 1 inputs except via shared VDD/GND. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 1.8 V systems - e.g., 0–1.8 V sensor output digitized directly by 1.8 V ADC. |
| 10 nA shutdown current per channel | Extends battery life in intermittent-sampling systems such as wireless sensor nodes or portable meters. |
| 20 μA supply current per channel | Permits integration of multiple op-amps in space-constrained, low-quiescent-current designs without thermal penalty. |
| Specified operation down to 1.8 V | Guarantees functionality at end-of-life battery voltage - eliminates need for voltage boosters in coin-cell or AA-powered devices. |
| Industrial temperature range (−40°C to 85°C) | Validated performance for deployment in uncontrolled environments including factory automation and outdoor instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2762IDR | Same electrical specs; MSOP-8 package (3 mm × 3 mm), tape-and-reel only; 54.2°C/W θJA vs 104°C/W for DIP. | Preferred for automated SMT assembly; unsuitable for hand-soldered prototypes or breadboards. | Select TLV2762IDR for volume production where board space and reflow compatibility are critical. |
| LPV521MG/NOPB | Lower supply current (320 nA), lower bandwidth (15.5 kHz), no shutdown pin; SC70-5 package (single-channel only). | Not drop-in: requires two devices for dual function; lacks shutdown control and rail-to-rail output swing at 1.8 V. | Choose LPV521MG/NOPB only when extreme ultra-low power dominates over bandwidth and dual-channel integration. |
Compared with TLV2762IDR, TLV2762IP offers through-hole mounting and higher thermal resistance for lab validation, while LPV521MG/NOPB trades off bandwidth and integration for nanoampere quiescent current - making TLV2762IP the optimal balance of micropower, dual-channel functionality, shutdown control, and 1.8 V operability.

FAQ
What is the maximum recommended supply voltage for TLV2762IP?
The absolute maximum supply voltage for TLV2762IP is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V may cause parametric degradation or reliability risk. The device is characterized and guaranteed across this range, including at 1.8 V (end-of-life two-AA battery voltage) and 2.4 V (nominal NiMH voltage).
Does TLV2762IP support true rail-to-rail output swing at 1.8 V supply?
Yes, TLV2762IP delivers rail-to-rail output swing at 1.8 V supply: high-level output voltage (VOH) is typically 1.79 V at 100 μA sink, and low-level output voltage (VOL) is typically 25 mV at 100 μA source - representing <1.5% headroom from each rail. This is confirmed in the Electrical Characteristics table for VDD = 1.8 V, TA = 25°C.
How does the shutdown pin (Pin 5) function on TLV2762IP?
Pin 5 (SHDN) is an active-low control: pulling it to GND disables both amplifiers and reduces total supply current to 10 nA (5 nA per channel). Tying SHDN to VDD enables normal operation. The pin has CMOS-compatible thresholds - VIH ≥ 2 V (for VDD ≥ 2.7 V) and VIL ≤ 0.6 V - and exhibits <1 pA leakage at 25°C per datasheet Section "Shutdown Characteristics".
Can TLV2762IP drive capacitive loads without oscillation?
TLV2762IP is stable with ≤10 pF capacitive load in unity-gain configuration. For larger loads (e.g., ADC input capacitance or long traces), a series nulling resistor (RNULL ≥ 20 Ω) between amplifier output and load is required to maintain phase margin >63°, as specified in the "Driving a Capacitive Load" application note (Figure 31) of the TLV276x datasheet.
What is the input offset voltage drift specification for TLV2762IP?
The input offset voltage drift (αVIO) for TLV2762IP is 9 μV/°C maximum, measured across the full industrial temperature range (−40°C to 85°C) with RL = 300 kΩ and RS = 50 Ω. This low drift ensures minimal calibration drift in precision sensor interfaces - for example, contributing <0.9 mV error over a 100°C span at room-temperature calibrated offset of 550 μV.
