Product details
Overview
TLC083AIN 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 shutdown functionality. It operates from a single 4.5 V to 16 V supply across –40°C to 125°C, and is used in precision audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring rail-to-rail input (VICR = GND to VDD–2 V) and robust output current.
For engineers reviewing the TLC083AIN datasheet, TLC083AIN pinout, TLC083AIN application, or TLC083AIN equivalent, key selection criteria include its dual-channel configuration with independent shutdown control per channel, 8.5 nV/√Hz input voltage noise, 19 V/µs negative slew rate, and compatibility with 14-pin PDIP packaging for through-hole prototyping and legacy industrial PCBs.
Technical Context
The TLC083AIN integrates a low-noise CMOS front end with a high-drive bipolar output stage, enabling simultaneous high AC performance (10 MHz GBW, 16–19 V/µs slew rates) and strong DC precision (60 µV max input offset voltage, 1.2 µV/°C drift). Its BiMOS architecture supports single-supply operation while maintaining ground-referenced common-mode input range.
It features two independent shutdown pins (pins 6 and 13), each controlling one amplifier channel's bias current and output state. The device delivers 55 mA sink and 57 mA source current into loads, with guaranteed performance over full industrial temperature range and supply voltages up to 16 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact dual-path signal processing without stacking discrete op-amps. |
| GBW | 10 MHz - supports stable closed-loop gain ≥10 at 1 MHz for audio and data acquisition front ends. |
| Slew Rate (SR–) | 19 V/µs - ensures faithful reproduction of fast transients in pulse amplification and active filtering. |
| Output Drive | ±57 mA - drives 600 Ω loads directly, eliminating external buffer stages in line-driver applications. |
| Input Noise | 8.5 nV/√Hz - preserves SNR in low-level sensor interfaces such as strain gauge or thermopile amplifiers. |
| Shutdown Current | 125 µA/channel - reduces system standby power in battery-backed instrumentation and automotive modules. |
| Supply Range | 4.5 V to 16 V - interoperates with 5 V, 12 V, and 15 V industrial rails without level-shifting. |
Pinout & Package
Package: 14-pin plastic DIP (PDIP), through-hole mount, 0.3-inch width, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - capable of sourcing/sinking ±57 mA into resistive or capacitive loads. |
| 2 | 1IN– | Inverting input of Channel A - high-impedance CMOS node (1 TΩ typical) for precision feedback networks. |
| 3 | 1IN+ | Non-inverting input of Channel A - accepts common-mode signals from GND to VDD–2 V. |
| 4 | GND | Analog ground reference - must be low-impedance connection to minimize noise coupling between channels. |
| 5 | VDD | Positive supply rail - powers both amplifiers and internal bias circuitry; bypass capacitor required. |
| 6 | 1/2SHDN | Channel A shutdown control - logic-low (<0.8 V) disables Channel A; open or high enables operation. |
| 7 | 2IN+ | Non-inverting input of Channel B - electrically isolated from Channel A inputs for differential pair use. |
| 8 | 2IN– | Inverting input of Channel B - matched offset and bias characteristics to Channel A for dual-path symmetry. |
| 9 | 2OUT | Amplifier B output - independently driven; no crosstalk impact on Channel A when loaded. |
| 10 | 2/1SHDN | Channel B shutdown control - separate logic input allows asymmetric power management per channel. |
| 11 | NC | No internal connection - unused pin; leave unconnected or tie to GND for mechanical stability. |
| 12 | NC | No internal connection - unused pin; no electrical function. |
| 13 | NC | No internal connection - unused pin; not bonded internally. |
| 14 | NC | No internal connection - unused pin; no thermal or ESD role. |
Key Features
| Feature | Design Value |
|---|---|

| Independent dual-channel shutdown | Enables dynamic power gating of individual amplifiers in multi-stage analog chains without affecting adjacent signal paths. |
| Ground-sensing input range | Supports direct interfacing to 0 V-referenced sensors (e.g., bridge transducers) without level-shifting circuitry. |
| High-output-current capability | Drives 600 Ω lines or 250 Ω loads at full swing, reducing need for external buffers in audio and test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CP | Lower bandwidth (3 MHz), higher input offset (10 mV max), no shutdown, JFET input (higher IB). | Lacks shutdown and high-output drive; suitable only for low-speed, low-precision legacy designs. | Select TL082CP only if cost sensitivity outweighs performance needs and existing layout uses 8-pin SOIC/DIP footprint. |
| OPA2340UA | Rail-to-rail I/O, lower noise (7 nV/√Hz), but limited output drive (25 mA), no shutdown, narrower supply (2.7–5.5 V). | Optimized for low-voltage portable systems; cannot replace TLC083AIN in 12 V industrial or automotive rails. | Choose OPA2340UA for battery-powered 3.3 V signal chains where rail-to-rail swing is critical and load current <25 mA. |
Compared with TL082CP and OPA2340UA, the TLC083AIN uniquely combines industrial-grade temperature range, high-output drive, shutdown control, and 10 MHz bandwidth in a 14-pin PDIP package-making it irreplaceable in 5–16 V systems demanding both precision and power delivery.

FAQ
What is the operating temperature range of the TLC083AIN?
The TLC083AIN is rated for operation from –40°C to +125°C, making it suitable for under-hood automotive applications, industrial control cabinets, and outdoor equipment where ambient temperatures exceed commercial-grade limits. This extended range is confirmed in the "Recommended Operating Conditions" table of the official TI datasheet SLOS254F.
Does the TLC083AIN support true single-supply operation with input down to ground?
Yes, the TLC083AIN supports true single-supply operation with a common-mode input voltage range from GND to VDD–2 V. This allows direct interfacing with ground-referenced sensors like strain gauges or potentiometers without level-shifting circuitry, as verified in the Electrical Characteristics tables for VICR at both 5 V and 12 V supplies.
How does the shutdown feature work on the TLC083AIN?
The TLC083AIN has two dedicated shutdown pins: pin 6 (1/2SHDN) controls Channel A, and pin 10 (2/1SHDN) controls Channel B. Applying a logic-low voltage ≤0.8 V to either pin reduces that channel's supply current to 125 µA while placing its output in high-impedance state-enabling independent power gating per channel as documented in the Operating Characteristics section.
What is the maximum output current capability of the TLC083AIN?
The TLC083AIN delivers ±57 mA output current-57 mA sourced at VDD–1.5 V and 55 mA sunk at 0.5 V-under typical conditions. This is validated in the "Features" list and Electrical Characteristics tables, enabling direct drive of 600 Ω lines or moderate-power transducers without external buffers.
Is the TLC083AIN pin-compatible with other devices in the TLC08x family?
No-the TLC083AIN uses a 14-pin PDIP package with unique pin assignments including dual shutdown controls and NC pins, differing from the 8-pin TLC082 and 10-pin MSOP variants. Pin compatibility is not claimed in the Family Package Table or pin diagrams; substitution requires PCB layout revision.
