Product details
Overview
TLC082CD from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V. It features low input offset voltage (60 µV typ), 16 V/µs positive slew rate, and ultralow 125 µA/channel shutdown current - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.
For engineers reviewing the TLC082CD datasheet, TLC082CD pinout, TLC082CD application, or TLC082CD equivalent, key selection criteria include its rail-to-rail input capability (VICR = GND to VDD–2 V), high-current output stage, CMOS-input low-noise performance (8.5 nV/√Hz), and SOIC-8 package compatibility with legacy TL082 layouts.
Technical Context
The TLC082CD employs a BiMOS architecture combining a low-noise, high-impedance CMOS front end with a high-drive bipolar output stage - delivering simultaneous improvements in bandwidth (10 MHz), output current (±55 mA), and input offset (60 µV typ) over TL08x predecessors. Its design supports stable operation with capacitive loads up to 50 pF and ensures common-mode input range includes ground across full temperature range (0°C to 70°C).
Unlike members of the same family (e.g., TLC083), the TLC082CD lacks shutdown functionality and uses an 8-pin SOIC package with dual independent op-amp channels sharing no internal logic control lines. Its differential input resistance exceeds 1000 GΩ, and supply rejection remains ≥80 dB across 4.5–16 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and ultrasonic frequencies without gain roll-off. |
| Output Drive | ±55 mA - drives heavy loads like 600 Ω audio lines or multiple ADC inputs without external buffers. |
| Slew Rate | +16 V/µs / –19 V/µs - supports fast transient response in pulse amplification and active filter applications. |
| Input Offset Voltage | 60 µV typical - minimizes DC error in precision instrumentation and sensor signal chains. |
| Supply Range | 4.5 V to 16 V single supply - simplifies power architecture in battery-powered and industrial 12 V systems. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - preserves SNR in low-level signal amplification (e.g., thermocouple, strain gauge). |
| Shutdown Current | Not applicable - TLC082CD has no shutdown pin; always active (unlike TLC080/TLC083). |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, standard JEDEC outline. Pin 1 marked by beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |

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 input offset (3 mV max), no rail-to-rail input (VICR = ±12 V min), 10 mA output drive. | Legacy dual op-amp for cost-sensitive, non-precision designs where speed and drive are secondary. | Select TL082CD only when existing PCB layout mandates pin compatibility and performance requirements are relaxed. |
| OPA2340UA | Rail-to-rail I/O, lower noise (7 nV/√Hz), but lower output drive (30 mA), narrower supply range (2.7–5.5 V), SOIC-8 package. | Optimized for low-voltage, low-power portable instrumentation - not suitable for 12 V industrial systems. | Choose OPA2340UA for battery-powered devices requiring rail-to-rail output swing and ultra-low supply voltage. |
Compared with TL082CD and OPA2340UA, the TLC082CD uniquely balances high-speed (10 MHz), high-drive (±55 mA), and wide-supply (4.5–16 V) operation in a standard SOIC-8 footprint - making it the optimal upgrade path for TL082-based designs needing improved dynamic performance without board redesign.

FAQ
What is the operating temperature range for the TLC082CD?
The TLC082CD is rated for commercial operation from 0°C to 70°C, as indicated by the "C" suffix in the part number. This range is validated per TI's SLOS254F datasheet and applies to all electrical specifications unless otherwise noted. The device is not qualified for extended industrial temperatures (–40°C to 125°C), which require the "I" suffix variant (e.g., TLC082ID). Thermal derating guidelines and junction temperature limits (150°C max) remain applicable under continuous operation.
Does the TLC082CD support shutdown mode?
No, the TLC082CD does not include a shutdown function. Unlike TLC080CD or TLC083CD, it lacks a SHDN pin and draws full supply current (1.9 mA/channel typical) at all times. This is confirmed by the family package table and pinout diagrams in the SLOS254F datasheet, where TLC082 entries show "-" under the Shutdown column. For low-power applications requiring standby, consider TLC080CD or TLC083CD instead.
What is the maximum capacitive load the TLC082CD can drive stably?
The TLC082CD maintains stability with capacitive loads up to 50 pF, as verified by phase margin measurements (≥32° at 25°C with CL = 50 pF, RL = 10 kΩ). Driving larger capacitive loads (e.g., >100 pF) risks peaking or oscillation unless compensated via series output resistance or feedback network adjustment. The datasheet's Figure 19 confirms this limit across supply voltages (5 V and 12 V) and temperature extremes.
Can the TLC082CD operate from a 3.3 V supply?
No, the TLC082CD requires a minimum supply voltage of 4.5 V per the Absolute Maximum Ratings and Recommended Operating Conditions tables in SLOS254F. Operation below 4.5 V may result in undefined behavior, reduced output swing, or failure to meet specified parameters such as bandwidth or output drive. For 3.3 V systems, consider TI's OPAx340 or TLV246x families, which are explicitly characterized down to 2.7 V.
Is the TLC082CD pin-compatible with the TL082CP or TL082CD?
Yes, the TLC082CD is pin-compatible with TL082CD and TL082CP in the SOIC-8 (D) and PDIP-8 (P) packages, respectively. Both share identical pin assignments (1OUT, 1IN–, 1IN+, GND, 2IN+, 2IN–, 2OUT, VDD) and footprint dimensions. However, due to differences in bandwidth, output drive, and input stage architecture, system-level validation is required to confirm functional equivalence in existing TL082 designs.
