Texas Instruments TLC083CDGQR

Overview

TLC083CDGQR from Texas Instruments is a dual-channel, wide-bandwidth BiMOS operational amplifier with 10 MHz gain-bandwidth product, ±57 mA high-output drive capability, and rail-to-rail input common-mode range (GND to VDD–2 V) - designed for single-supply audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring robust output swing and fast settling.

For engineers reviewing the TLC083CDGQR datasheet, TLC083CDGQR pinout, TLC083CDGQR application, or TLC083CDGQR equivalent, this device delivers verified 16 V/µs positive slew rate, 125 µA shutdown current per channel, 8.5 nV/√Hz input voltage noise, and MSOP-10 packaging - critical for low-noise, high-drive analog front-ends in space-constrained designs.

Technical Context

The TLC083CDGQR integrates a low-noise CMOS input stage with a high-current bipolar output stage, enabling simultaneous high input impedance (>1 GΩ), low input bias current (≤100 pA), and ±55 mA sink/source capability at 0.5 V and VDD–1.5 V respectively. Its BiMOS architecture ensures stable operation across 4.5 V to 16 V supply rails and –40°C to 125°C temperature range.

It features independent shutdown control per amplifier (pins 1 and 8), allowing selective channel disablement without affecting the other channel's bias or output state. The device maintains 32° phase margin into 50 pF capacitive loads and achieves 0.18 µs settling time (0.01%) for 1 V step at AV = –1, supporting precision closed-loop configurations.

FAQ

What is the maximum supply voltage rating for the TLC083CDGQR?

The TLC083CDGQR has an absolute maximum supply voltage (VDD) rating of 17 V. Operation beyond this limit risks permanent damage. Recommended operating range is 4.5 V to 16 V, making it compatible with standard 12 V automotive systems and industrial 15 V rails. Derating is required above 25°C ambient per the dissipation rating table (θJA = 52.3°C/W).

Does the TLC083CDGQR support rail-to-rail input operation?

Yes, the TLC083CDGQR supports rail-to-rail input common-mode voltage from GND to VDD–2 V. This allows direct interfacing with sensors and DACs operating at ground-referenced outputs without level-shifting circuitry. Note that full rail-to-rail output swing is not supported - output typically swings within 1.5 V of VDD and 0.5 V of GND under load.

How does the shutdown function operate on the TLC083CDGQR?

The TLC083CDGQR provides independent shutdown control for each amplifier via Pins 1 (CH1 SHDN) and 8 (CH2 SHDN). Each is active-low: applying ≤0.8 V disables the respective channel, reducing its supply current to 125 µA. Both channels remain fully functional when SHDN pins are ≥2 V. No external pull-up resistors are required - internal logic ensures defined states during power-up.

What is the thermal performance of the TLC083CDGQR in MSOP-10 (DGQ) package?

The TLC083CDGQR in DGQ package has θJA = 52.3°C/W and θJC = 4.7°C/W. With proper PCB layout - including a solid thermal pad soldered to ≥1 cm² copper area - it dissipates up to 2.39 W at TA ≤ 25°C. At 70°C ambient, derated power drops to ~1.4 W. TI recommends using the exposed PowerPAD™ for optimal thermal performance and reliability in continuous high-current operation.

Can the TLC083CDGQR drive a 600 Ω load at 2 VPP without distortion?

Yes, the TLC083CDGQR delivers ±57 mA output current, enabling clean 2 VPP sine waves into 600 Ω loads (requiring ±3.3 mA) with THD+N < 0.005% at 1 kHz (VDD = 12 V). Its 16 V/µs slew rate prevents slew-induced distortion, and 10 MHz GBW ensures flat frequency response across the audio band.
