Product details
Overview
TLC082CDGN from Texas Instruments is a dual-channel, wide-bandwidth (10 MHz), high-output-drive BiMOS operational amplifier optimized for single-supply operation from 4.5 V to 16 V. It delivers ±57 mA output drive, 16 V/µs positive slew rate, and 60 µV typical input offset voltage, enabling precision signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC082CDGN datasheet, TLC082CDGN pinout, TLC082CDGN application, or TLC082CDGN equivalent, key selection criteria include its rail-to-rail input common-mode range (GND to VDD–2 V), ultralow 1.9 mA/channel quiescent current, and MSOP-8 PowerPAD™ package thermal performance for high-density PCB layouts.
Technical Context
The TLC082CDGN integrates a low-noise CMOS front end with a high-drive bipolar output stage, enabling simultaneous high AC performance (10 MHz GBW, 8.5 nV/√Hz input noise) and robust DC accuracy (60 µV VIO, 1000 GΩ differential input resistance). Its BiMOS architecture supports stable operation with capacitive loads up to 50 pF while maintaining ≥32° phase margin.
Unlike legacy TL08x predecessors, the TLC082CDGN ensures ground-sensing input common-mode range and achieves 300% higher bandwidth and 60% lower voltage noise. It operates across 0°C to 70°C (C-suffix) and supports shutdown mode only in TLC080/TLC083/TLC085 variants - the TLC082CDGN lacks shutdown functionality per family table.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz gain-bandwidth product enables stable unity-gain buffer or 10× inverting amplifier up to 1 MHz. |
| Output Drive | ±57 mA sourcing/sinking capability drives 600 Ω audio loads or 10 kΩ instrumentation circuits without external buffers. |
| Slew Rate | 16 V/µs (SR+) and 19 V/µs (SR–) support fast settling of 1 V step signals in <0.4 µs at AV = –1. |
| Supply Range | 4.5 V to 16 V single supply simplifies power design versus dual-rail op-amps in battery-powered or industrial systems. |
| Input Offset | 60 µV typical VIO ensures ≤0.6 mV error in 10 V full-scale 12-bit ADC front ends without trimming. |
| Quiescent Current | 1.9 mA per channel allows dual-op-amp use in low-power portable devices with <4 mA total analog supply draw. |
| Input Noise | 8.5 nV/√Hz at 1 kHz enables clean amplification of microvolt-level sensor signals (e.g., thermocouples, strain gauges). |
Pinout & Package
Package: 8-pin MSOP (DGN) with exposed thermal pad (PowerPAD™), 3.0 mm × 3.0 mm footprint, 0.65 mm pitch, JEDEC MO-187AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output node for first op-amp; capable of ±57 mA drive into resistive or moderate capacitive loads. |
| 2 | Channel 1 Inverting Input | Inverting input terminal; high-impedance CMOS node (1000 GΩ) minimizes bias current errors in high-Z feedback networks. |
| 3 | Channel 1 Non-Inverting Input | Non-inverting input terminal; supports rail-to-rail common-mode range (GND to VDD–2 V) for single-supply sensor interfacing. |
| 4 | Ground | Analog ground reference; must be low-impedance connection to minimize noise coupling between channels. |
| 5 | Positive Supply (VDD) | Single positive supply input (4.5–16 V); internal regulation ensures stable biasing across voltage range. |
| 6 | Channel 2 Output | Amplified output node for second op-amp; electrically isolated from Channel 1 but shares VDD and GND. |
| 7 | Channel 2 Inverting Input | Inverting input for second amplifier; identical electrical characteristics to Pin 2. |
| 8 | Channel 2 Non-Inverting Input | Non-inverting input for second amplifier; identical electrical characteristics to Pin 3. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS Process Architecture | Combines CMOS input stage (low IB, low noise) with bipolar output stage (high IOUT, low Zo) for optimal trade-off. |
| Rail-to-Rail Input Common-Mode Range | GND to VDD–2 V enables direct interfacing with unipolar sensors (e.g., 0–5 V pressure transducers) without level-shifting. |
| High Output Current Capability | ±57 mA drive eliminates need for external output buffers in line-driver or actuator-control applications. |
| Low Input Voltage Noise | 8.5 nV/√Hz at 1 kHz reduces integrated noise in 10 Hz–100 kHz bandwidths to <1.3 µV RMS for precision DC-coupled paths. |
| Stable with Capacitive Loads | Maintains ≥32° phase margin with 50 pF load, supporting direct driving of ADC input capacitance or long cables. |

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 |
|---|---|---|---|
| TLV2462IDR | Lower bandwidth (6.4 MHz), lower output drive (±30 mA), rail-to-rail I/O, 0.55 mA/channel IDD. | Better suited for ultra-low-power battery apps; insufficient drive for 600 Ω audio loads. | Select when power budget <1 mA/channel is critical and audio drive not required. |
| OPA2350UA | Higher bandwidth (38 MHz), lower noise (7 nV/√Hz), rail-to-rail I/O, 4.9 mA/channel IDD, no PowerPAD. | Superior for high-speed data acquisition; higher quiescent current limits portable use. | Select when >10 MHz small-signal bandwidth and lowest noise are mandatory. |
Compared with TLV2462IDR and OPA2350UA, the TLC082CDGN uniquely balances 10 MHz bandwidth, ±57 mA drive, and 1.9 mA/channel consumption in an MSOP-8 PowerPAD package-making it optimal for space-constrained industrial and automotive signal chains requiring robust output capability without excessive power penalty.

FAQ
What is the operating temperature range for the TLC082CDGN?
The TLC082CDGN is rated for commercial temperature 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 does not support extended industrial (–40°C to 125°C) operation - that variant is designated TLC082IDGN.
Does the TLC082CDGN include a shutdown feature?
No, the TLC082CDGN does not include a shutdown function. Per the Family Package Table in the SLOS254F datasheet, shutdown capability is only available on TLC080, TLC083, and TLC085 variants. The TLC082CDGN has no SHDN pin and draws 1.9 mA per channel continuously under normal operation.
What is the maximum capacitive load the TLC082CDGN can drive stably?
The TLC082CDGN maintains ≥32° phase margin with up to 50 pF capacitive load when configured as a unity-gain follower with RL = 10 kΩ, as verified in Figure 19 of the SLOS254F datasheet. Driving larger capacitive loads (e.g., >100 pF) requires isolation resistors or compensation networks to prevent peaking or oscillation.
Can the TLC082CDGN operate from a 3.3 V supply?
No, the TLC082CDGN requires a minimum supply voltage of 4.5 V per the Recommended Operating Conditions table in SLOS254F. Operation below 4.5 V may result in degraded output swing, increased distortion, or failure to meet specified bandwidth and slew rate performance.
Is the TLC082CDGN pin-compatible with the TL082CP?
No, the TLC082CDGN (MSOP-8) is not pin-compatible with the TL082CP (PDIP-8) due to different package footprints and pin assignments. While both are dual op-amps with identical functional pinouts (1OUT, 2IN–, 2IN+, GND, VDD, 1OUT, 1IN–, 1IN+), the MSOP-8 DGN package has 0.65 mm pitch and thermal pad, whereas PDIP-8 uses 2.54 mm pitch and no thermal pad - requiring PCB redesign for substitution.
