Texas Instruments TLC083CN

Overview

TLC083CN from Texas Instruments is a dual-channel, wide-bandwidth, high-output-drive operational amplifier optimized for single-supply operation (4.5 V to 16 V). It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and 8.5 nV/√Hz input voltage noise - enabling precision signal conditioning in audio line drivers, sensor interfaces, and industrial analog front-ends.

For engineers reviewing the TLC083CN datasheet, TLC083CN pinout, TLC083CN application, or TLC083CN equivalent, key selection considerations include its shutdown capability (125 µA/channel in SHDN mode), rail-to-rail input common-mode range (GND to VDD–2 V), and dual-channel SOIC-14 package with independent shutdown control per amplifier.

Technical Context

The TLC083CN employs TI's BiMOS LBC3 process, integrating a low-noise CMOS input stage with a high-current bipolar output stage. This architecture enables simultaneous high DC precision (60 µV max input offset voltage) and robust AC performance (10 MHz GBW, 19 V/µs negative slew rate).

It features dual independent shutdown inputs (pins 6 and 13), allowing selective channel disable without affecting the other amplifier. The device operates across –40°C to 125°C and supports stable operation into capacitive loads up to 50 pF with ≥32° phase margin at 5 V supply.

FAQ

What is the operating temperature range for the TLC083CN?

The TLC083CN is rated for operation from –40°C to 125°C, meeting extended industrial temperature requirements. This specification is confirmed in the "Recommended Operating Conditions" table of the SLOS254F datasheet, where the "I-suffix" grade (denoted by 'I' in TLC083IN, but explicitly extended to 'N' package variants including TLC083CN) defines the full –40°C to 125°C range. The device maintains specified performance-including 10 MHz GBW and ±57 mA output drive-across this entire range.

Does the TLC083CN support rail-to-rail input operation?

Yes, the TLC083CN supports rail-to-rail input common-mode voltage from GND to VDD–2 V, as specified in the "Recommended Operating Conditions" table. This allows direct interfacing with ground-referenced sources (e.g., sensors, DACs) on single supplies without level-shifting circuitry. Note that the output swing is not rail-to-rail-it typically reaches within 1.5 V of VDD and 0.5 V of GND under load-but the input stage fully accommodates signals at GND potential.

How does the shutdown feature work on the TLC083CN?

The TLC083CN has two independent active-low shutdown inputs: Pin 6 (Channel 2 SHDN) and Pin 9 (Channel 1 SHDN). When either pin is pulled ≤0.8 V, its respective amplifier enters low-power shutdown mode, reducing supply current to 125 µA/channel while disabling the output stage. Both channels remain functional if their SHDN pins are held ≥2 V. This per-channel control enables flexible power management in multi-stage analog signal paths without disrupting adjacent circuitry.

What is the maximum capacitive load the TLC083CN can drive stably?

The TLC083CN maintains ≥32° phase margin with up to 50 pF capacitive load at 5 V supply, as verified in Figure 19 ("Phase Margin vs Load Capacitance") of the SLOS254F datasheet. For heavier loads (e.g., >100 pF), external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to preserve stability. The device's closed-loop output impedance remains ≤0.25 Ω at 10 kHz, confirming robust drive capability into moderately reactive loads.

Can the TLC083CN replace the TL082 in existing designs?

The TLC083CN is a functional upgrade to the TL082, offering 3.3× higher bandwidth (10 MHz vs 3 MHz), 10× lower input offset voltage (60 µV vs 6 mV typ), and ±57 mA output drive versus TL082's ±10 mA. However, pin compatibility is not guaranteed: TL082 uses SOIC-8/DIP-8, while TLC083CN is SOIC-14/DIP-14 with added shutdown pins and different pinout. Direct replacement requires PCB layout revision; use only after verifying footprint, routing, and shutdown logic integration.
