Texas Instruments TLV2762IDGKR

Overview

TLV2762IDGKR from Texas Instruments is a dual-channel, micropower, rail-to-rail input/output operational amplifier with shutdown control, 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 ultralow 10 nA shutdown current. It is designed for battery-powered sensor signal conditioning in industrial temperature range (−40°C to 85°C).

For engineers reviewing the TLV2762IDGKR datasheet, TLV2762IDGKR pinout, TLV2762IDGKR application, or TLV2762IDGKR equivalent, key selection criteria include micropower operation at 1.8 V, rail-to-rail I/O swing, integrated shutdown functionality, and MSOP-8 packaging for space-constrained analog front-ends.

Technical Context

The TLV2762IDGKR uses CMOS input stage architecture enabling rail-to-rail common-mode input voltage range (−0.2 V to VDD + 0.2 V) and ultra-low input bias current (3 pA typical). Its internal shutdown logic activates below 0.6 V (VIL) and deactivates above 2 V (VIH) on the SHDN pin, delivering 10 nA per-channel quiescent current in disabled state.

It features unity-gain stable operation with 63° phase margin into 100 pF load, supports capacitive loads up to 10 pF without external compensation, and maintains 550 μV typical input offset voltage across −40°C to 85°C. Output drive capability is ±5 mA at 1.8 V, with rail-to-rail output swing within 25 mV of rails at 100 μA load.

Key Specifications

FAQ

What is the maximum recommended supply voltage for TLV2762IDGKR?

The absolute maximum supply voltage for TLV2762IDGKR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V per the datasheet. Exceeding 3.6 V risks parametric degradation and reduced long-term reliability, especially at elevated temperatures. Operation at 3.6 V is valid and commonly used for headroom in battery-powered systems with fresh alkaline cells.

Does TLV2762IDGKR support true rail-to-rail output swing at 1.8 V supply?

Yes, TLV2762IDGKR achieves rail-to-rail output swing at 1.8 V supply: high-level output reaches ≥1.77 V (within 25 mV of VDD) and low-level output drops to ≤30 mV (within 30 mV of GND) at 100 μA load, as specified in the Electrical Characteristics table. This enables full utilization of the 1.8 V supply for ADC interfacing without external level shifting.

How does the shutdown function behave on TLV2762IDGKR?

The TLV2762IDGKR shutdown pin (Pin 5) is active-high: driving it ≥2 V enables both amplifiers, while pulling it ≤0.6 V disables them and reduces total supply current to 10 nA per channel. Turn-on time is 5 μs and turn-off time is 0.8 μs, measured from SHDN edge to IDD reaching 50% of final value - enabling fast wake-up in duty-cycled sensor systems.

Can TLV2762IDGKR drive capacitive loads without oscillation?

TLV2762IDGKR is unity-gain stable with up to 10 pF capacitive load at the output. For loads >10 pF, a series null resistor (RNULL ≥20 Ω) must be added between the output pin and the load capacitance to maintain ≥63° phase margin and prevent ringing or oscillation - as confirmed in the "Driving a Capacitive Load" application note section of the datasheet.

What is the input common-mode voltage range for TLV2762IDGKR at 1.8 V supply?

At 1.8 V supply, the input common-mode voltage range for TLV2762IDGKR is −0.2 V to VDD + 0.2 V, i.e., −0.2 V to +2.0 V. This rail-to-rail input capability allows direct interface with sensors or DACs operating beyond the supply rails, such as grounded thermistors or bipolar-output references, without external clamping or level-shifting circuitry.
