Product details
Overview
TLC082ID from Texas Instruments is a dual-channel, wide-bandwidth BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V), delivering 10 MHz gain-bandwidth, ±57 mA output drive, and 16 V/µs positive slew rate. It operates across –40°C to 125°C and is used in high-fidelity audio line drivers, industrial sensor signal conditioning, and automotive body control modules requiring rail-to-rail input capability and robust load driving.
For engineers reviewing the TLC082ID datasheet, TLC082ID pinout, TLC082ID application, or TLC082ID equivalent, key selection criteria include guaranteed ground-sensing common-mode input range (VICR = GND to VDD–2 V), low 8.5 nV/√Hz input noise, 60 µV typical input offset voltage, and compatibility with MSOP-8, SOIC-8, and PDIP-8 packages - all critical for precision analog front-ends in harsh environments.
Technical Context
The TLC082ID integrates a low-noise CMOS input stage with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling simultaneous high impedance (>1 TΩ differential input resistance), low input bias current (<700 pA), and strong output sourcing/sinking (57 mA/55 mA). Its architecture supports stable unity-gain operation with ≥32° phase margin into 50 pF loads.
No internal shutdown function is present - unlike TLC080/TLC083 - confirming the TLC082ID is a fixed-function dual op-amp without enable/disable control logic. The device features offset nulling pins (pins 1 and 8) and ensures full-spec performance over extended temperature (–40°C to 125°C) at supply voltages as low as 4.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - enables compact two-stage amplification or differential pair implementation without external matching. |
| GBW | 10 MHz - supports stable closed-loop gain up to 10× at 1 MHz or unity gain at 10 MHz for fast signal processing. |
| SR+ | 16 V/µs - ensures ≤100 ns settling for 1-V step with <0.1% error in follower configuration. |
| VIO (typ) | 60 µV - reduces DC error to <0.001% of 6-V full-scale, critical for 16-bit ADC driver accuracy. |
| VICR | GND to VDD–2 V - allows direct interfacing with 0-V referenced sensors (e.g., thermocouples, bridge outputs) on single supply. |
| IOH/IOL | 57 mA / 55 mA - drives 600-Ω loads to ±5 V swing at 5 V supply, eliminating need for external buffer stages. |
| Vn | 8.5 nV/√Hz @ 1 kHz - maintains SNR >98 dB in 20-kHz audio band, suitable for preamplifier stages. |
Pinout & Package
Package: SOIC-8 (D), PDIP-8 (P), or MSOP-8 (DGN); all variants share identical 8-pin dual op-amp pinout with offset null capability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (A) | Connects to potentiometer wiper for trimming input offset voltage of Channel A. |
| 2 | Inverting Input (A) | High-impedance (1 TΩ) node for feedback network attachment in inverting configurations. |
| 3 | Non-inverting Input (A) | Accepts ground-referenced signals directly; common-mode range includes 0 V. |
| 4 | GND | Analog ground reference; must be low-impedance connection to minimize PSRR degradation. |
| 5 | Non-inverting Input (B) | Independent input for second channel; no crosstalk coupling per datasheet (–80 dB @ 10 kHz). |
| 6 | Inverting Input (B) | Supports independent gain-setting resistors; no shared bias network with Channel A. |
| 7 | Output (B) | Capable of sourcing 57 mA into VDD–1.5 V or sinking 55 mA to 0.5 V - verified at 125°C. |
| 8 | VDD | Single positive supply input; accepts 4.5–16 V; no negative rail required. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CD | Lower bandwidth (3 MHz), higher VIO (1.5 mV max), no ground-sensing VICR (min = ±4 V), 13 V/µs SR. | Not suitable for 0-V referenced sensors or high-speed 10-MHz loops; requires dual supply for full input range. | Select TL082CD only if cost sensitivity outweighs performance needs and dual supply is available. |
| OPA2340UA | Rail-to-rail output (not input), lower noise (7 nV/√Hz), lower supply current (800 µA/ch), but only 5.5 MHz GBW and ±20 mA IO. | Preferred for ultra-low-power battery devices where output swing to rails is mandatory, but insufficient for high-current loads. | Choose OPA2340UA when RRO and sub-1-mA quiescent current are prioritized over drive strength and bandwidth. |
Compared with TL082CD and OPA2340UA, the TLC082ID uniquely balances 10-MHz bandwidth, ground-sensing input, ±57-mA drive, and extended temperature operation - making it the only option among the three qualified for automotive-grade single-supply sensor front-ends demanding both precision and power.

FAQ
What is the operating temperature range for the TLC082ID?
The TLC082ID is rated for continuous operation from –40°C to 125°C, with all electrical specifications fully guaranteed across this extended industrial temperature range. This makes the TLC082ID suitable for under-hood automotive applications, factory automation sensors, and outdoor industrial equipment where ambient temperatures exceed standard commercial limits. The "I" suffix explicitly denotes this extended grade, distinguishing it from the "C" (0°C to 70°C) version.
Does the TLC082ID include a shutdown feature?
No, the TLC082ID does not include a shutdown feature. Unlike the TLC080 and TLC083 variants which integrate SHDN pins, the TLC082ID is a fixed-function dual op-amp with no enable/disable control logic. Its pinout omits any shutdown terminal, and the datasheet confirms shutdown current (IDD(SHDN)) applies only to TLC080/TLC083/TLC085. Therefore, the TLC082ID draws its full 1.9 mA per channel supply current at all times when powered.
What package options are available for the TLC082ID?
The TLC082ID is offered in three industry-standard packages: SOIC-8 (D), PDIP-8 (P), and MSOP-8 (DGN). All share identical pinout and electrical characteristics. The MSOP-8 variant provides the smallest footprint (3 mm × 3 mm), while SOIC-8 offers optimal manufacturability and thermal performance (θJA = 176°C/W), and PDIP-8 supports through-hole prototyping. No QFN or TSSOP variants exist for the TLC082ID.
Can the TLC082ID drive a 600-Ω load to ±5 V on a 5-V supply?
Yes, the TLC082ID can drive a 600-Ω load to ±5 V output swing on a 5-V supply. Its specified output current (IOH = 57 mA at VDD–1.5 V, IOL = 55 mA at 0.5 V) exceeds the 8.3 mA required for ±5 V into 600 Ω. Measured VOH/VOL data at VDD = 5 V confirms high-level output reaches ≥3.2 V at –50 mA and low-level output falls to ≤0.7 V at +50 mA - enabling full ±5 V compliance with appropriate headroom design.
How does the TLC082ID compare to the TLC082CD in terms of input offset voltage?
The TLC082ID and TLC082CD share identical input offset voltage specifications: 390 µV (max) at 25°C and 3000 µV (max) over full temperature range. Both variants belong to the same silicon family and process (LBC3 BiCMOS), with the "I" and "C" suffixes indicating only temperature grading - not parametric differentiation. Therefore, the TLC082ID maintains the same 60 µV typical VIO as the TLC082CD, but guarantees performance across –40°C to 125°C instead of 0°C to 70°C.
