Texas Instruments TLV2622IDGKR

Overview

TLV2622IDGKR from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for low-power, wide-bandwidth single-supply operation. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, and 27 nV/√Hz input voltage noise at 800 µA per channel supply current, operating from 2.7 V to 5.5 V over –40°C to +125°C. It is used in high-resolution data acquisition front-ends interfacing with SAR ADCs.

For engineers reviewing the TLV2622IDGKR datasheet, TLV2622IDGKR pinout, TLV2622IDGKR application, or TLV2622IDGKR equivalent, this page provides verified electrical specifications, MSOP-8 package terminal mapping, industrial-grade temperature performance, and validated alternative options for precision analog signal conditioning designs.

Technical Context

The TLV2622IDGKR implements a CMOS input stage with rail-to-rail output swing and common-mode input range extending to VDD + 0.2 V, enabling direct interface with positive-rail-referenced sensors and DAC outputs. Its 11-MHz unity-gain bandwidth and 10-V/µs slew rate support stable closed-loop operation into 2-kΩ loads with 10-pF capacitive load.

It features active shutdown (SHDN pin) reducing supply current to 4 µA per channel, with turn-on/turn-off times of 4.5 µs and 200 ns respectively. Phase margin is 63° under standard test conditions (RL = 2 kΩ, CL = 10 pF), ensuring robust stability in unity-gain follower and gain-of-2 configurations.

FAQ

What is the maximum capacitive load the TLV2622IDGKR can drive while maintaining stability?

The TLV2622IDGKR maintains 63° phase margin with a 10-pF capacitive load and 2-kΩ resistive load per the datasheet test condition. Driving >100 pF requires external isolation resistance (e.g., 10–100 Ω in series with the output) to prevent peaking or oscillation, as phase margin degrades to <45° beyond that point. Always verify stability with actual PCB parasitics using transient simulation.

Does the TLV2622IDGKR support true single-supply operation with input signals near ground?

Yes, the TLV2622IDGKR supports true single-supply operation: its input common-mode range extends from 1 V above ground to VDD + 0.2 V, and its output swings within 30 mV of GND. However, inputs below 1 V may exhibit increased offset and reduced CMRR; for ground-sensing applications, consider AC-coupling or a negative bias rail.

How does shutdown mode affect output state in the TLV2622IDGKR?

In shutdown mode (SHDN ≤ 0.4 V), the TLV2622IDGKR disables both amplifiers and places OUT A and OUT B in high-impedance (Hi-Z) state-neither sourcing nor sinking current. This prevents back-driving of downstream circuitry and eliminates loading on shared buses or ADC inputs during sleep cycles.

Can the TLV2622IDGKR be used in a unity-gain stable configuration with a 10-kΩ feedback resistor?

Yes, the TLV2622IDGKR is unity-gain stable. With a 10-kΩ feedback resistor and no additional capacitance, it achieves 63° phase margin per the datasheet. However, layout parasitics (especially >1 pF at the inverting input node) can reduce margin; keep feedback traces short and avoid ground-plane cuts beneath the amplifier.

What is the typical input offset voltage drift over temperature for the TLV2622IDGKR?

The TLV2622IDGKR has a typical input offset voltage drift of 3 µV/°C, measured across the full –40°C to +125°C range. This low drift ensures minimal gain error accumulation in precision transducer interfaces, contributing to <±10 µV total offset variation over industrial temperature extremes.
