Product details
Overview
TLC083ID from Texas Instruments is a dual-channel, wide-bandwidth, high-output-drive operational amplifier designed 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 TLC083ID datasheet, TLC083ID pinout, TLC083ID application, or TLC083ID equivalent, this BiMOS op-amp supports rail-to-rail input (VICR includes GND), shutdown control, and MSOP-10 packaging - critical for space-constrained, low-power, high-fidelity analog systems requiring stable DC accuracy and fast transient response.
Technical Context
The TLC083ID integrates a low-noise CMOS front end with a high-current bipolar output stage, enabling simultaneous high input impedance (>1 GΩ differential resistance), ultralow input noise (8.5 nV/√Hz), and robust ±55 mA sinking capability. Its BiMOS architecture ensures guaranteed common-mode input range to ground and improved PSRR (≥80 dB) over legacy TL08x devices.
It features independent shutdown control per channel (1/2SHDN pin), allowing dynamic power management in multi-stage amplification chains. The device operates across –40°C to +125°C and maintains stable phase margin (≥32°) with up to 50 pF capacitive load - supporting direct driving of ADC inputs and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and low-speed data acquisition frequencies. |
| Output Drive | ±57 mA - drives heavy loads like 600 Ω audio lines or multiple parallel ADC inputs without external buffers. |
| Slew Rate | +16 V/µs / –19 V/µs - supports fast settling for pulse and step-response-critical applications (e.g., sensor burst readout). |
| Input Offset Voltage | 60 µV typ - reduces DC error in precision instrumentation and closed-loop transducer signal chains. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and battery-backed industrial rails without level-shifting. |
| Shutdown Current | 125 µA/channel - cuts quiescent power by >93% during idle periods in energy-sensitive embedded systems. |
| Input Noise | 8.5 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor amplification (e.g., thermocouples, strain gauges). |
Pinout & Package
Package: 10-pin MSOP (DGQ) - 3 mm × 3 mm footprint with exposed thermal pad for enhanced power dissipation in compact PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Channel 1 output - directly drives downstream stages or feedback networks with ±57 mA capability. |
| 2 | 1IN– | Inverting input for Channel 1 - accepts differential or single-ended signals with 1 GΩ input resistance. |
| 3 | 1IN+ | Non-inverting input for Channel 1 - supports rail-to-rail common-mode input down to GND. |
| 4 | VDD | Positive supply rail - powers both channels and internal bias circuitry; decoupling required at pin. |
| 5 | 2IN+ | Non-inverting input for Channel 2 - electrically isolated from Channel 1; enables dual-path signal processing. |
| 6 | 2IN– | Inverting input for Channel 2 - matched performance to Pin 2; supports independent gain configuration. |
| 7 | 2OUT | Channel 2 output - identical drive strength and slew rate as Pin 1; usable for stereo or redundant paths. |
| 8 | 1/2SHDN | Shared shutdown control - logic-low disables both amplifiers simultaneously; reduces IDD to 125 µA total. |
| 9 | GND | Analog ground reference - must be connected to low-impedance system ground plane for noise immunity. |
| 10 | NC | No internal connection - left unconnected; no routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (VICR = GND to VDD–2 V) | Enables direct interfacing with 0 V-referenced sensors (e.g., bridge-based pressure transducers) without level-shifting. |
| High output current (±57 mA) | Eliminates need for external buffer stages when driving low-impedance loads like 600 Ω audio lines or SAR ADC sample capacitors. |
| Low input offset drift (1.2 µV/°C) | Maintains calibration stability over automotive temperature ranges (–40°C to +125°C) without frequent recalibration. |
| Ultralow shutdown current (125 µA/channel) | Extends battery life in portable test equipment by enabling per-cycle amplifier enable/disable in data acquisition sequences. |
| BiMOS process architecture | Combines CMOS input stage (low IB, low noise) with bipolar output (high drive, fast recovery) - no design trade-off between precision and power. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-output-drive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2350EA/250 | Lower bandwidth (38 MHz), lower output current (±50 mA), rail-to-rail I/O, higher quiescent current (4.9 mA/ch) | Better for high-speed, low-voltage (2.7–5.5 V) applications; less suitable for 12 V industrial loads | Select when speed > bandwidth and supply < 5.5 V; avoid for 12 V loop drivers or high-current loads |
| LMH6629MA | Higher bandwidth (800 MHz), higher slew rate (1100 V/µs), lower output current (±30 mA), no shutdown | Optimized for RF/IF signal chain buffering; lacks shutdown and rail-to-rail input | Select only for GHz-range small-signal amplification; not a functional substitute for TLC083ID's precision + drive combination |
Compared with OPA2350EA/250 and LMH6629MA, the TLC083ID uniquely balances 10 MHz bandwidth, ±57 mA drive, rail-to-rail input, and 125 µA shutdown - making it the only option among the three that meets simultaneous requirements for industrial 12 V signal conditioning, low-power standby, and DC precision.

FAQ
What is the operating temperature range for the TLC083ID?
The TLC083ID is rated for operation from –40°C to +125°C, qualifying it for under-hood automotive, industrial control, and harsh-environment applications. This extended temperature grade is confirmed in the "TLC082 and TLC083 AVAILABLE OPTIONS" table, where the "I" suffix denotes the –40°C to +125°C range, and all electrical characteristics in the datasheet are specified across this full range unless otherwise noted.
Does the TLC083ID support rail-to-rail input operation?
Yes, the TLC083ID supports rail-to-rail input common-mode voltage from GND to VDD–2 V, as explicitly stated in the "RECOMMENDED OPERATING CONDITIONS" table. This allows direct interfacing with 0 V-referenced sensors and eliminates the need for input biasing networks in single-supply configurations - a key differentiator from legacy TL08x op-amps.
What is the function of the 1/2SHDN pin on the TLC083ID?
The 1/2SHDN pin (Pin 8) is a shared shutdown control input that disables both amplifier channels simultaneously when pulled to ≤0.8 V. In shutdown mode, total supply current drops to 125 µA (62.5 µA per channel), as verified in the "ELECTRICAL CHARACTERISTICS" table under IDD(SHDN). This feature enables dynamic power management in battery-powered or duty-cycled systems.
Can the TLC083ID drive a 600 Ω load at 12 V supply?
Yes, the TLC083ID can drive a 600 Ω load at 12 V supply. With ±57 mA output current capability and VOH ≥10.3 V at IOH = –50 mA (per datasheet Table, VDD = 12 V), it delivers >10 V swing into 600 Ω - sufficient for professional audio line-level standards (e.g., +24 dBu ≈ 12.3 VPP). Its phase margin remains stable (≥37°) with 50 pF load, ensuring reliable operation without oscillation.
Is the TLC083ID pin-compatible with other TLC08x devices?
No, the TLC083ID is not pin-compatible with TLC080/1/2 or TLC084/5. As shown in the "FAMILY PACKAGE TABLE", TLC083 uses a 10-pin MSOP (DGQ) or 14-pin PDIP (N) package, while TLC080/1/2 use 8-pin packages and TLC084/5 use 14- or 16-pin variants. The TLC083ID's 10-pin DGQ layout (with dedicated 1/2SHDN and NC pins) is unique within the family and requires specific PCB footprint design.
