Texas Instruments TLV2622IDGK

Overview

TLV2622IDGK 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 while consuming only 800 µA per channel at 2.7–5.5 V supply. Its input common-mode range includes the positive rail (up to VDD + 0.2 V), enabling direct interfacing with high-side-referenced sensors in battery-powered data acquisition systems.

For engineers reviewing the TLV2622IDGK datasheet, TLV2622IDGK pinout, TLV2622IDGK application, or TLV2622IDGK equivalent, key selection criteria include its industrial-grade temperature range (–40°C to 125°C), ultralow 4 µA/channel shutdown current, and compatibility with lithium-ion (2.7 V min) and MSP430 microcontroller supply rails - critical for portable instrumentation and precision analog front-ends.

Technical Context

The TLV2622IDGK implements a CMOS input stage with rail-to-rail output swing and a positive-rail-inclusive input common-mode range (1 V to VDD + 0.2 V), enabling direct sensing of signals referenced to VDD. Its 11-MHz unity-gain bandwidth and 10-V/µs slew rate support high-fidelity signal conditioning in 12-bit+ SAR ADC driver applications.

It features independent shutdown control via Pin 8 (1/2SHDN), reducing total supply current to 4 µA/channel in disabled state. Phase margin is maintained at 63° with 2-kΩ load and 10-pF capacitive load, ensuring stable operation without external compensation in most unity-gain configurations.

FAQ

What is the maximum capacitive load the TLV2622IDGK can drive without instability?

The TLV2622IDGK maintains 63° phase margin with a 10-pF capacitive load and 2-kΩ resistive load at 25°C. Driving >100 pF requires isolation resistance (e.g., 100 Ω in series with output) or reduced closed-loop gain to preserve stability - verified in Figure 16 of the SLOS251D datasheet.

Does the TLV2622IDGK support true single-supply operation down to 2.7 V?

Yes. The TLV2622IDGK is fully specified from 2.7 V to 5.5 V supply, with guaranteed performance including 11-MHz GBW, 10-V/µs slew rate, and rail-to-rail output swing at 2.7 V - validated across –40°C to 125°C per the "Recommended Operating Conditions" table.

How does the shutdown function of the TLV2622IDGK behave during power-up?

The TLV2622IDGK's 1/2SHDN pin (Pin 8) defaults to active-high logic; the amplifiers power up enabled when SHDN ≥ 2 V (VIH threshold). To prevent output glitches, tie SHDN to VDD through a pull-up resistor or assert it high before applying analog inputs - timing details in Figure 23.

Can the TLV2622IDGK be used to buffer a 0–5 V DAC output driving a 10-kΩ load?

Yes. With VDD = 5 V, the TLV2622IDGK delivers rail-to-rail output swing (VOL = 25 mV, VOH = 4.95 V at 1 mA) into 10-kΩ, meeting 0–5 V full-scale requirements. Its 1-V/µs small-signal settling time (Figure 19) ensures <1-µs settling to 0.1% for step changes.

Is the TLV2622IDGK pin-compatible with other dual op-amps in VSSOP-8 packages?

No. The TLV2622IDGK uses a non-standard VSSOP-8 pinout (e.g., GND on Pin 4, SHDN on Pin 8). It is not pin-compatible with industry-standard dual op-amps like LMV358 or MCP6022 - verify against Figure 10 in SLOS251D before PCB layout.
