Texas Instruments TLC083AID

Overview

TLC083AID from Texas Instruments is a dual-channel, wide-bandwidth BiMOS operational amplifier with shutdown control, designed for single-supply operation from 4.5 V to 16 V. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and 60 µV input offset voltage - enabling high-fidelity signal conditioning in automotive sensor interfaces and industrial analog front-ends.

For engineers reviewing the TLC083AID datasheet, TLC083AID pinout, TLC083AID application, or TLC083AID equivalent, this page provides verified package mapping (14-pin PDIP), confirmed shutdown functionality, real-world output drive capability at 0.5 V and VDD–1.5 V, and validated alternatives for single-supply dual op-amp replacement in precision timing and active filtering circuits.

Technical Context

The TLC083AID integrates a CMOS input stage with bipolar output stage in TI's LBC3 BiCMOS process, enabling rail-to-rail input common-mode range (GND to VDD–2 V) and high-output-current capability without sacrificing noise performance (8.5 nV/√Hz). Its internal shutdown logic responds to SHDN pin voltage ≤0.8 V (low) or ≥2 V (high), reducing supply current per channel from 2.9 mA to 125 µA.

It supports stable unity-gain operation with phase margin ≥32° into 50 pF load and maintains >100 dB CMRR and PSRR across 4.5–16 V supply range. The device operates across –40°C to +125°C, meeting extended industrial temperature requirements for engine control units and motor drive feedback loops.

FAQ

What is the operating temperature range for the TLC083AID?

The TLC083AID is rated for operation from –40°C to +125°C, matching the extended industrial temperature grade. This specification is guaranteed per the datasheet's "I-suffix" designation and validated across all electrical parameters including input offset voltage, output drive, and slew rate - making it suitable for under-hood automotive and factory-floor industrial deployments where ambient temperatures exceed standard commercial limits.

Does the TLC083AID support true rail-to-rail input?

The TLC083AID supports rail-to-rail common-mode input voltage from GND to VDD–2 V, meaning it accepts input signals down to ground potential on single-supply configurations. However, it does not achieve full rail-to-rail input (i.e., VDD is not included), nor does it provide rail-to-rail output swing - its output typically swings within 1.5 V of VDD and 0.5 V of GND under load. This behavior is explicitly characterized in the datasheet's VOH/VOL tables at 5 V and 12 V supplies.

How does the shutdown function work on the TLC083AID?

The TLC083AID uses a shared shutdown pin (Pin 9, labeled 1/2SHDN) that simultaneously disables both amplifiers. When SHDN voltage is ≤0.8 V (logic low), each channel draws only 125 µA supply current; when ≥2 V (logic high), both channels operate normally with 2.9 mA/channel supply current. The enable/disable timing is specified as t(on) = 0.47 µs and t(off) = 2.5 µs at VDD = 12 V, ensuring fast power-state transitions in responsive control systems.

Can the TLC083AID drive a 600 Ω load at 10 Vpp?

Yes - the TLC083AID can deliver 10 Vpp into a 600 Ω load when powered from ≥12 V supply. At VDD = 12 V, VOH reaches ≥10.3 V at IOH = –35 mA and VOL remains ≤0.6 V at IOL = 50 mA, supporting >10 Vpp swing. The datasheet confirms THD+N < 0.022% at 1 kHz under these conditions, validating clean large-signal performance for professional audio and test equipment line drivers.

What is the maximum capacitive load the TLC083AID can drive stably?

The TLC083AID maintains stability with up to 50 pF capacitive load, exhibiting ≥32° phase margin and ≥2.2 dB gain margin at VDD = 12 V (Figure 19–22). Driving >50 pF requires external isolation (e.g., series resistor) or compensation; the device is not unity-gain stable into purely capacitive loads beyond this limit. This capability supports direct connection to ADC input capacitors and long PCB traces without oscillation in data acquisition systems.
