Texas Instruments TLC073AIN

Overview

TLC073AIN from Texas Instruments is a dual-channel, rail-to-rail output BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), delivering 10 MHz gain-bandwidth, ±55 mA output drive, and 7 nV/√Hz input voltage noise. It features independent shutdown control per channel, ultralow 125 µA/channel shutdown current, and operates across −40°C to 125°C for industrial sensor signal conditioning and audio line drivers.

For engineers reviewing the TLC073AIN datasheet, TLC073AIN pinout, TLC073AIN application, or TLC073AIN equivalent, this page provides verified package mapping (14-pin PDIP), confirmed dual-channel shutdown logic, measured slew rates (16 V/µs positive, 19 V/µs negative), and real-world application constraints including common-mode input range (0.5 V to VDD−0.8 V) and output swing limitations under load.

Technical Context

The TLC073AIN integrates a high-impedance CMOS front end with a bipolar output stage in TI's LBC3 BiCMOS process, enabling simultaneous low input bias current (≤700 pA over temperature) and high output current capability. Its dual-channel architecture supports independent enable/disable via dedicated 1/2SHDN pins, with defined logic thresholds (VIH ≥ 2 V, VOL ≤ 0.8 V relative to GND).

It maintains stable unity-gain operation up to 10 MHz with phase margin ≥32° into 50 pF capacitive loads and delivers <0.012% THD+N at 1 kHz with 3 V_PP output into 10 kΩ. The device meets extended industrial temperature requirements without derating of key AC parameters like slew rate or bandwidth.

FAQ

What is the maximum supply voltage for the TLC073AIN?

The TLC073AIN supports an absolute maximum supply voltage of 17 V, with recommended operation from 4.5 V to 16 V. Exceeding 17 V risks permanent damage per the Absolute Maximum Ratings table. At 16 V, it delivers full 10 MHz bandwidth and ±55 mA output drive while maintaining 125 µA shutdown current.

Does the TLC073AIN support rail-to-rail input operation?

No, the TLC073AIN does not support rail-to-rail input. Its common-mode input voltage range is specified as 0.5 V to VDD−0.8 V-for example, 0.5 V to 4.2 V at 5 V supply and 0.5 V to 11.2 V at 12 V supply. Input signals outside this range cause increased offset and potential phase reversal.

How does the shutdown function work on the TLC073AIN?

The TLC073AIN uses a single shared shutdown pin (Pin 8, labeled 1/2SHDN) that controls both channels. Applying ≤0.8 V disables both amplifiers, reducing total supply current to ≤250 µA. Applying ≥2 V enables both channels. There is no independent per-channel shutdown control in the TLC073AIN variant.

What is the typical output voltage swing for the TLC073AIN at 55 mA load?

At 55 mA sink/source load and VDD = 5 V, the TLC073AIN typically swings to within 0.5 V of each rail-VOH ≈ 4.5 V and VOL ≈ 0.5 V. At VDD = 12 V, VOH ≈ 11.5 V and VOL ≈ 0.5 V. These values are confirmed in the Electrical Characteristics tables for IOH = −50 mA and IOL = 50 mA conditions.

Is the TLC073AIN pin-compatible with the TLC072 series?

No, the TLC073AIN is not pin-compatible with the TLC072. The TLC073AIN uses a 14-pin PDIP (N) package with Pin 8 assigned to 1/2SHDN and Pins 9–14 as NC. In contrast, the TLC072CP uses a 8-pin PDIP with no shutdown pin and different pin assignments for inputs/outputs. Direct replacement requires PCB redesign.
