Texas Instruments TLV2762IDR

Overview

TLV2762IDR 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, 20 μA per channel supply current, and 550 μV input offset voltage across −40°C to 85°C industrial temperature range-ideal for low-voltage battery-powered sensor signal conditioning.

For engineers reviewing the TLV2762IDR datasheet, TLV2762IDR pinout, TLV2762IDR application, or TLV2762IDR equivalent, key selection criteria include ultralow shutdown current (10 nA/channel), rail-to-rail I/O swing at 1.8 V, CMOS input stage enabling mega-ohm gain networks, and MSOP-8 packaging for space-constrained portable instrumentation.

Technical Context

The TLV2762IDR integrates two independent CMOS op-amp channels in a single MSOP-8 package, each featuring rail-to-rail input common-mode range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing. Its micropower architecture achieves 20 μA/channel quiescent current while maintaining 0.20 V/μs slew rate and 500 kHz unity-gain bandwidth at 1.8 V.

Shutdown functionality is implemented via dedicated SHDN pin per channel (pin 5 in MSOP-8), reducing supply current to 10 nA/channel when driven low. Input bias current is 3 pA typical, enabling high-impedance transducer interfacing without significant error from resistor-divider loading.

Key Specifications

Pinout & Package

TLV2762IDR is housed in an 8-pin MSOP (DGK) package, 3.0 mm × 3.0 mm × 1.0 mm profile, with exposed thermal pad (not electrically connected). Pin 1 is marked by a dot; pin numbering follows standard MSOP convention (counterclockwise from top-left corner).

FAQ

What is the maximum recommended supply voltage for TLV2762IDR?

The absolute maximum supply voltage for TLV2762IDR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V may cause accelerated parametric drift or reliability degradation. The device is characterized and specified only within this 1.8–3.6 V window, including all DC and AC parameters such as input offset voltage, bandwidth, and slew rate. Operating at 3.6 V maximizes output drive capability, while 1.8 V enables compatibility with end-of-life alkaline or lithium primary cells.

Does TLV2762IDR support true rail-to-rail input at 1.8 V supply?

Yes, TLV2762IDR supports true rail-to-rail input with a common-mode voltage range of −0.2 V to VDD + 0.2 V. At 1.8 V supply, this means inputs can be accepted from −0.2 V to +2.0 V. This extended range enables direct interfacing with sensors that output below ground (e.g., thermocouples with cold-junction compensation) or above VDD (e.g., level-shifted digital signals), without external clamping or biasing networks. The specification is verified across the full −40°C to +85°C temperature range.

How does the shutdown function operate on TLV2762IDR?

The TLV2762IDR features independent shutdown control for each channel via dedicated SHDN pins (pin 5 for Channel 1, pin 10 for Channel 2 in MSOP-8). Driving SHDN ≤0.6 V disables the corresponding amplifier, reducing its supply current to 10 nA. Driving SHDN ≥2 V enables normal operation. Turnon/turnoff times are 5 μs and 0.8 μs respectively, measured from SHDN edge to IDD reaching 50% of final value. No external pull-up is required-the internal logic threshold is fixed relative to GND.

What is the output drive capability of TLV2762IDR at 1.8 V supply?

At 1.8 V supply, TLV2762IDR delivers ±5 mA output current while maintaining rail-to-rail swing. Specifically, VOH is ≥1.77 V at IOH = −100 μA and ≥1.725 V at IOH = −500 μA; VOL is ≤25 mV at IOL = 100 μA and ≤75 mV at IOL = 500 μA. Short-circuit output current is ±10 mA. These values are specified over the full −40°C to +85°C range and enable direct driving of ADC reference buffers, LED indicators, or low-power comparators without external gain stages.

Can TLV2762IDR drive capacitive loads without instability?

TLV2762IDR is stable with capacitive loads ≤10 pF when configured as a unity-gain follower. For larger loads (e.g., ADC input capacitance, cable capacitance), a series nulling resistor (RNULL ≥20 Ω) must be placed between the output and load to maintain phase margin >60°. This is confirmed by Figure 18 in the datasheet, which shows phase margin degrading from 63° to <45° as load capacitance increases beyond 10 pF with RNULL = 0 Ω. Layout best practices-including local 0.1 μF decoupling and minimized output trace length-further improve stability.
