Texas Instruments TLV2622IP

Overview

TLV2622IP from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation from 2.7 V to 5.5 V. It delivers 11 MHz gain-bandwidth, 10 V/µs slew rate, 27 nV/√Hz input voltage noise, 800 µA per channel supply current, and supports industrial temperature range (–40°C to 125°C). It is used in high-resolution data acquisition front-ends interfacing with SAR ADCs.

For engineers reviewing the TLV2622IP datasheet, TLV2622IP pinout, TLV2622IP application, or TLV2622IP equivalent, key selection criteria include rail-to-rail output swing, positive-rail-inclusive input common-mode range (VICR = 1 V to VDD + 0.2 V), ultralow shutdown current (4 µA/channel), low THD+N (0.002% at AV = 1), and MSOP/SOIC package compatibility for space-constrained signal conditioning.

Technical Context

The TLV2622IP implements a CMOS input stage with rail-to-rail output stage, enabling full dynamic range utilization in 3.3-V and Li-ion powered systems. Its input common-mode range extends to the positive supply rail, allowing direct sensing of signals referenced to VDD - critical for sensor biasing and current-sense amplifier configurations.

It features an integrated shutdown control (SHDN) pin that reduces supply current to 4 µA per channel while maintaining fast enable/disable timing (t_on = 4.5 µs at VDD = 2.7 V; t_off = 200 ns). The amplifier maintains stable unity-gain operation into 2-kΩ loads with 10-pF capacitive load, delivering 63° phase margin and 8-dB gain margin.

Key Specifications

Pinout & Package

TLV2622IP is packaged in an 8-pin plastic DIP (PDIP) with 0.300-inch body width, through-hole mounting, and industry-standard SOIC-compatible footprint. Pin 1 is located at the left end of the top row, identified by a molded bevel or dot.

FAQ

What is the maximum recommended supply voltage for TLV2622IP?

The absolute maximum supply voltage for TLV2622IP is 6 V, but the recommended operating range is 2.7 V to 5.5 V. Operation at 5.5 V is fully specified across the industrial temperature range (–40°C to 125°C), and the device is commonly used with 3.3-V or 5-V rails in data acquisition and sensor interface applications. Exceeding 5.5 V risks permanent damage.

Does TLV2622IP support rail-to-rail input operation?

No, TLV2622IP does not support rail-to-rail input - its common-mode input voltage range is specified from 1 V to VDD + 0.2 V. While this includes the positive supply rail (enabling VDD-referenced inputs), it excludes the negative rail (GND). For true rail-to-rail input capability, consider alternatives like the TLV2782IP, though it trades off bandwidth and noise performance.

How does the shutdown feature of TLV2622IP behave during power-up?

TLV2622IP powers up enabled by default: when VDD rises, the amplifier begins operating immediately unless SHDN is held low. The SHDN pin is active-low and requires <0.4 V to enter shutdown mode; at power-up, if SHDN is left floating or pulled high via ≥10-kΩ resistor, the device remains active. No external power-up sequencing is required for normal operation of TLV2622IP.

Can TLV2622IP drive a 10-nF capacitive load stably?

TLV2622IP is characterized for stability with ≤10-pF capacitive loads (CL = 10 pF, RL = 2 kΩ), delivering 63° phase margin. Driving 10-nF (10,000 pF) directly will cause severe peaking and potential oscillation. To drive larger capacitive loads, use a series isolation resistor (e.g., 10–100 Ω) between TLV2622IP output and the capacitor, or add a dedicated buffer stage - never operate TLV2622IP open-loop into >100 pF without compensation.

What is the input offset voltage specification for TLV2622IP over temperature?

TLV2622IP has a maximum input offset voltage (VIO) of 3500 µV at TA = 25°C and 4500 µV across the full industrial temperature range (–40°C to 125°C). Its typical VIO drift is 3 µV/°C, meaning offset can increase by ~300 µV over a 100°C span. For precision applications, system-level calibration or chopper-stabilized alternatives (e.g., TLC2652) may be needed where drift-critical performance is required.
