Product details
Overview
TLC083IN from Texas Instruments is a dual-channel, wide-bandwidth, high-output-drive operational amplifier optimized for single-supply operation across 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 typical input offset voltage - enabling precision signal conditioning in automotive sensor interfaces and industrial analog front-ends.
For engineers reviewing the TLC083IN datasheet, TLC083IN pinout, TLC083IN application, or TLC083IN equivalent, key selection criteria include its shutdown capability (SHDN pin), rail-to-rail input common-mode range (GND to VDD–2 V), extended temperature rating (–40°C to 125°C), and compatibility with 14-pin PDIP packaging for legacy board designs.
Technical Context
The TLC083IN employs TI's BiMOS LBC3 process, integrating a low-noise CMOS input stage (8.5 nV/√Hz) with a high-current bipolar output stage. This architecture enables simultaneous high dc precision (120 dB PSRR, 110 dB CMRR) and robust ac performance (10 MHz GBW, 19 V/µs negative slew rate).
It features active shutdown control (SHDN pin), allowing per-channel power gating with 125 µA/channel quiescent current in shutdown mode. The device supports true single-supply operation with VICR extending to ground and output swing within 0.5 V of rails under 50 mA load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - supports independent signal paths for differential sensing or multi-stage amplification |
| Gain-bandwidth product | 10 MHz - enables stable unity-gain buffer or closed-loop gain ≥10 at audio and ultrasonic frequencies |
| Output drive | ±57 mA - drives heavy loads (e.g., 600 Ω lines, capacitive DAC buffers) without external boost stages |
| Input offset voltage | 60 µV typical - reduces dc error in precision instrumentation and sensor signal chains |
| Supply voltage range | 4.5 V to 16 V - operates directly from 5 V, 12 V, or unregulated industrial rails |
| Operating temperature | –40°C to 125°C - qualified for under-hood automotive and industrial control environments |
| Shutdown current | 125 µA/channel - enables low-power sleep modes in battery-backed or energy-conscious systems |
Pinout & Package
Package: 14-pin plastic DIP (N package), through-hole mount, 0.3-inch width, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - capable of sourcing/sinking ±57 mA into resistive or capacitive loads |
| 2 | 1IN– | Inverting input of Channel 1 - high-impedance CMOS node (1 TΩ typical) for precision feedback networks |
| 3 | 1IN+ | Non-inverting input of Channel 1 - supports rail-to-rail common-mode input down to GND |
| 4 | GND | Analog ground reference - must be connected to system AGND plane for noise immunity |
| 5 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1; shares same supply domain |
| 6 | 2IN– | Inverting input of Channel 2 - matched bias current and offset characteristics to Pin 2 |
| 7 | 2OUT | Output of Channel 2 - independently controllable; supports dual-sensor or dual-path signal processing |
| 8 | VDD | Positive supply rail - accepts 4.5 V to 16 V; decoupling capacitor required at pin |
| 9 | 1/2SHDN | Shared shutdown control - logic-low (≤0.8 V) disables both amplifiers; logic-high (≥2 V) enables |
| 10–14 | NC / Not connected | No internal connection - pins 10–14 are unused; must remain unconnected or grounded per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Wide bandwidth + high output drive | 10 MHz GBW with ±57 mA output enables driving 600 Ω lines at 100 kHz without distortion |
| Rail-to-rail input common-mode range | VICR includes GND (0 V) up to VDD–2 V - eliminates level-shifting for single-supply sensor interfacing |
| Low input noise voltage | 8.5 nV/√Hz at 1 kHz - preserves SNR in microphone preamps and strain-gauge amplifiers |
| Integrated shutdown control | Single SHDN pin disables both channels simultaneously, reducing total supply current to 250 µA max |
| High PSRR and CMRR | 100 dB PSRR and 110 dB CMRR - rejects supply ripple and common-mode interference in noisy industrial settings |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, single-supply op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CP | Lower bandwidth (3 MHz), no shutdown, higher input offset (3 mV max), 14-pin PDIP | Lacks rail-to-rail input, unsuitable for GND-referenced sensors; lower drive (±10 mA) | Select only when cost sensitivity outweighs performance needs and shutdown is unnecessary |
| OPA2340UA | Rail-to-rail I/O, 5.5 MHz GBW, 20 mA output, 14-pin SOIC, no shutdown | Better input/output swing but lower drive and no SHDN pin; not rated beyond 85°C | Prefer for low-voltage (2.7–5 V) precision apps where thermal margin is not critical |
Compared with TL082CP and OPA2340UA, the TLC083IN uniquely combines extended temperature operation (–40°C to 125°C), integrated shutdown, and high output drive (±57 mA) - making it the only option among the three qualified for automotive under-hood and industrial high-current analog signal conditioning.

FAQ
What is the maximum supply voltage rating for the TLC083IN?
The TLC083IN has an absolute maximum supply voltage (VDD) of 17 V. Its recommended operating range is 4.5 V to 16 V, making it compatible with standard 5 V, 12 V, and unregulated industrial rails. Operation above 16 V risks permanent damage and violates TI's specified conditions.
Does the TLC083IN support rail-to-rail input operation?
Yes, the TLC083IN supports rail-to-rail input common-mode voltage from GND (0 V) up to VDD–2 V. This allows direct interfacing with ground-referenced sensors like thermistors or bridge circuits without level-shifting circuitry - a key advantage over older TL08x devices.
How does the shutdown function work on the TLC083IN?
The TLC083IN uses a shared shutdown pin (Pin 9, labeled 1/2SHDN). Applying ≤0.8 V disables both amplifiers, reducing total supply current to ≤250 µA. A voltage ≥2 V enables normal operation. No external pull-up is required, but a clean logic signal is essential to avoid partial enable states.
What is the typical output current capability of the TLC083IN?
The TLC083IN delivers ±57 mA source/sink current per channel at VDD–1.5 V (high-side) and 0.5 V (low-side), verified across the full –40°C to 125°C temperature range. This enables direct driving of 600 Ω lines, capacitive loads up to 1000 pF, and LED indicators without external buffers.
Is the TLC083IN pin-compatible with other devices in the TLC08x family?
The TLC083IN (14-pin PDIP) shares the same pinout as TLC082CN and TLC084IN in the N package, but differs from TLC080/1/2/3 in MSOP or SOIC variants. Pin compatibility is limited to the 14-pin DIP footprint; substitution requires verification of channel count, shutdown presence, and thermal specifications.
