Texas Instruments TLC082IDR

Overview

TLC082IDR from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V. It features low input offset voltage (60 µV typ), high slew rate (16 V/µs positive, 19 V/µs negative), and ultralow shutdown current (125 µA/channel), enabling use in precision audio line drivers and industrial sensor signal conditioning.

For engineers reviewing the TLC082IDR datasheet, TLC082IDR pinout, TLC082IDR application, or TLC082IDR equivalent, key selection criteria include its rail-to-rail input common-mode range (GND to VDD–2 V), output drive capability into 600 Ω loads, and guaranteed performance across –40°C to +125°C industrial temperature range.

Technical Context

The TLC082IDR employs a BiMOS architecture combining a low-noise CMOS front end (8.5 nV/√Hz input voltage noise) with a high-current bipolar output stage. This enables simultaneous high DC precision (60 µV VIO, 1000 GΩ differential input resistance) and robust AC performance (10 MHz GBW, 19 V/µs SR–).

It operates without external compensation over capacitive loads up to 50 pF and supports stable unity-gain follower configurations. The device lacks shutdown functionality-confirmed by absence of SHDN pin in TLC082 package diagrams and omission from TLC082 row in FAMILY PACKAGE TABLE.

Key Specifications

Pinout & Package

TLC082IDR is supplied in an 8-pin SOIC (D) package with standard industry footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is marked by a molded dot or beveled edge indicator.

Manufacturer

Texas Instruments is a global semiconductor leader specializing in analog and embedded processing technologies, with decades of expertise in precision op-amps and signal-chain solutions.

The TLC08x family was designed specifically for high-fidelity, high-drive single-supply applications-including audio, instrumentation, and industrial control-where BiFET predecessors lacked bandwidth and output capability.

FAQ

What is the maximum load capacitance the TLC082IDR can drive stably in unity-gain configuration?

The TLC082IDR maintains stability with capacitive loads up to 50 pF in unity-gain follower configuration, as verified by phase margin measurements (≥32° at CL = 50 pF, RL = 10 kΩ). For larger loads, external isolation resistor (e.g., 10–50 Ω in series with output) is recommended to preserve stability without degrading bandwidth significantly. This behavior is documented in Figure 19 and Figure 20 of the SLOS254F datasheet.

Does the TLC082IDR include a shutdown pin or power-down mode?

No, the TLC082IDR does not include a shutdown pin or power-down mode. Unlike TLC080 and TLC083 variants, the TLC082 has no SHDN terminal-confirmed by its 8-pin SOIC pinout diagram and explicit omission from the "SHUTDOWN" column in the FAMILY PACKAGE TABLE. Its quiescent supply current remains fixed at 1.9 mA per channel under normal operation.

What is the common-mode input voltage range for the TLC082IDR at 12 V supply?

At VDD = 12 V, the TLC082IDR supports a common-mode input voltage range from GND to VDD–2 V (i.e., 0 V to 10 V), as specified in the RECOMMENDED OPERATING CONDITIONS table. This rail-to-rail input capability enables direct interfacing with unipolar sensors and DACs without level-shifting circuitry.

Can the TLC082IDR operate from a 3.3 V supply?

No, the TLC082IDR is not rated for 3.3 V operation. Its absolute minimum supply voltage is 4.5 V, and recommended operating range starts at 4.5 V (per ABSOLUTE MAXIMUM RATINGS and RECOMMENDED OPERATING CONDITIONS). Attempting 3.3 V operation results in undefined behavior, degraded output swing, and potential failure to meet AC/DC specifications.

How does the input offset voltage of the TLC082IDR compare between 5 V and 12 V supplies?

The TLC082IDR's input offset voltage remains consistent across supply voltages: 390 µV typical (1400 µV max) at both VDD = 5 V and VDD = 12 V, as confirmed in ELECTRICAL CHARACTERISTICS tables for both conditions. This supply-insensitive VIO stems from its BiMOS architecture and ensures predictable DC accuracy regardless of system rail choice.
