Texas Instruments TLV2773ID

Overview

TLV2773ID from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for single-supply operation from 2.5 V to 5.5 V. It delivers 10.5 V/µs slew rate, 5.1 MHz gain-bandwidth product, 360 µV input offset voltage, and micropower shutdown (<1 µA per channel), enabling precision signal conditioning in automotive sensor interfaces and portable data acquisition systems.

For engineers reviewing the TLV2773ID datasheet, TLV2773ID pinout, TLV2773ID application, or TLV2773ID equivalent, key selection criteria include its −40°C to 125°C operating range, 2-pA input bias current, 17 nV/√Hz input noise, rail-to-rail output swing into 600-Ω loads, and integrated shutdown control per channel - critical for low-power, high-accuracy analog front-ends.

Technical Context

The TLV2773ID employs a CMOS input stage with differential pair topology, supporting rail-to-rail output via complementary push-pull output transistors. Its internal architecture enables stable unity-gain operation with 46° phase margin and 12 dB gain margin when driving 600-Ω loads with 100-pF capacitive load.

Each channel features independent shutdown logic referenced to VDD, with turnon/turnoff times of 2.4 µs and 444 ns (at AV = 5), respectively. The device is characterized across extended temperature ranges and supports single-supply configurations where common-mode input extends to GND and output swings within 100 mV of rails.

Key Specifications

FAQ

What is the maximum supply voltage rating for TLV2773ID?

The absolute maximum supply voltage for TLV2773ID is 7 V, as specified in the Absolute Maximum Ratings table. However, the recommended operating range is 2.5 V to 5.5 V. Operating above 5.5 V may cause parametric degradation or reliability issues, and TI does not guarantee performance beyond this range. Always use appropriate decoupling and avoid transient overvoltage conditions on the VDD pin.

Does TLV2773ID support true rail-to-rail input common-mode range?

No, TLV2773ID supports rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends from GND to VDD − 1.3 V at 25°C (e.g., 0 V to 3.7 V at VDD = 5 V). Inputs driven below GND or above VDD − 1.3 V may cause phase reversal or increased offset error. For full rail-to-rail input capability, consider TI's TLV9002 or similar devices.

How does the shutdown function behave on TLV2773ID?

TLV2773ID features two independent shutdown pins: 1SHDN (Pin 10) and 2SHDN (Pin 9). Driving either pin low disables the corresponding amplifier channel, reducing its supply current to <1 µA. The output enters high-impedance state. Both channels remain active when both pins are high. No external pull-up resistors are required - internal logic thresholds are compatible with standard CMOS/TTL levels.

Can TLV2773ID drive a 50-Ω load effectively?

TLV2773ID is not optimized for 50-Ω loads. Its datasheet specifies performance into 600-Ω loads (e.g., 0.005% THD+N, rail-to-rail swing). Driving 50 Ω would exceed its ±50-mA output current limit under most conditions and degrade linearity, slew rate, and thermal stability. For 50-Ω line driving, TI recommends dedicated high-speed buffers like THS3201 or LMH6702 instead of TLV2773ID.

Is TLV2773ID qualified for automotive applications?

Yes, TLV2773ID is offered in Q-Temp Automotive grade (I-suffix) and qualified to AEC-Q100 standards. It is characterized from −40°C to 125°C, supports PPAP documentation, and includes enhanced reliability testing for automotive use cases such as engine control, body electronics, and ADAS sensor interfaces. The "I" in TLV2773ID explicitly denotes this automotive qualification.
