Product details
Overview
TLC081CDR from Texas Instruments is a single-channel BiMOS operational amplifier optimized for wide-bandwidth, high-output-drive applications on single supplies. It delivers 10 MHz gain-bandwidth, ±57 mA output drive, 16 V/µs positive slew rate, and operates from 4.5 V to 16 V - enabling robust signal conditioning in audio line drivers and industrial sensor interfaces.
For engineers reviewing the TLC081CDR datasheet, TLC081CDR pinout, TLC081CDR application, or TLC081CDR equivalent, key selection criteria include its rail-to-rail input common-mode range (GND to VDD–2 V), ultralow 125 µA shutdown current per channel, and SOIC-8 package compatibility with space-constrained PCB layouts.
Technical Context
The TLC081CDR integrates a low-noise CMOS front end with a high-current bipolar output stage in TI's LBC3 BiCMOS process, enabling simultaneous high impedance (>1 TΩ differential input resistance), low input noise (8.5 nV/√Hz at 1 kHz), and strong load driving capability (55 mA sink / 57 mA source).
It features an internal offset nulling architecture with dedicated NULL pins, supports single-supply operation down to 4.5 V, and includes a logic-controlled shutdown mode (SHDN pin) that reduces supply current to 125 µA while maintaining fast turnon/turnoff times (0.47 µs / 2.5 µs at VDD = 12 V).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables stable closed-loop operation up to 100 kHz with gain ≥ 100. |
| Output Drive | ±57 mA - drives heavy loads like 600 Ω audio lines or capacitive DAC buffers without external boost. |
| Slew Rate | +16 V/µs / –19 V/µs - supports clean 10 VPP signals at >100 kHz without slewing distortion. |
| Supply Range | 4.5 V to 16 V - compatible with 5 V, 12 V, and battery-backed industrial rails. |
| Input Offset | 60 µV typical - minimizes DC error in precision transimpedance or instrumentation amplifier stages. |
| Shutdown Current | 125 µA per channel - enables low-power sleep modes in portable or always-on monitoring systems. |
| Input Noise | 8.5 nV/√Hz at 1 kHz - suitable for low-level sensor amplification where thermal noise dominates. |
Pinout & Package
Package: SOIC-8 (D package), surface-mount, 150 mil width, tape-and-reel (R suffix). Pin 1 marked by beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NULL | Offset null adjustment terminal - connects to external potentiometer for fine-tuning DC accuracy. |
| 2 | IN– | Inverting input - high-impedance node for feedback networks or differential configurations. |
| 3 | IN+ | Non-inverting input - accepts ground-referenced or rail-to-rail common-mode signals (GND to VDD–2 V). |
| 4 | GND | Analog ground reference - must be low-impedance connection to minimize noise coupling. |
| 5 | NC | No internal connection - left unconnected; no routing or stitching required. |
| 6 | VDD | Positive supply - accepts 4.5 V to 16 V; bypass capacitor (0.1 µF) recommended near pin. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking ±57 mA into resistive or moderate capacitive loads. |
| 8 | NULL | Second offset null terminal - completes external nulling circuit with Pin 1. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Operates with inputs from GND to VDD–2 V - eliminates level-shifting in single-supply sensor front ends. |
| High-output-drive bipolar output stage | Delivers ±57 mA into loads - replaces discrete output buffers in line-driver and actuator-control circuits. |
| Low-noise CMOS input stage | 8.5 nV/√Hz input voltage noise - preserves SNR in microphone preamps and strain-gauge amplifiers. |
| Logic-compatible shutdown control | SHDN pin accepts 0.8 V / 2.0 V thresholds - enables microcontroller-driven power gating with <1 µs latency. |
| Offset nulling terminals | Pins 1 and 8 support external trimming - achieves <100 µV system offset without calibration software. |
Applications
| Audio Line Driver | Industrial Sensor Signal Conditioning |
|---|---|
Use Scenario: Driving balanced/unbalanced analog audio signals over 10 m cables to mixing consoles or ADC inputs. IC Role / Device Role: Single-supply unity-gain buffer with high output current and low THD+N (0.005% at 1 kHz, 8 VPP). Use Value: Eliminates need for dual supplies or external emitter followers while maintaining <0.01% distortion at full scale. | Use Scenario: Amplifying low-level outputs from RTDs, thermocouples, or bridge-based pressure sensors in PLC I/O modules. IC Role / Device Role: Precision non-inverting amplifier with offset nulling and rail-to-rail input capability. Use Value: Enables direct interface to 0–5 V ADCs without level-shifting; 60 µV VIO ensures <0.1% measurement error at 50 mV full-scale. |

IC Role / Device Role: High-current voltage follower with shutdown control for energy-efficient standby states. Use Value: Sustains 10 mA into 1 kΩ loads while consuming only 125 µA in shutdown - extends battery life in remote I/O nodes. | Use Scenario: Conditioning signals from cabin temperature, humidity, or seat occupancy sensors before feeding to MCU ADCs. IC Role / Device Role: Single-supply op-amp operating across –40°C to 125°C with guaranteed VIO ≤ 1.5 mV (max). Use Value: Meets AEC-Q100 Grade 1 requirements without external compensation; 125°C operation supports under-hood proximity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA350UA | Lower 5.5 MHz bandwidth, lower 50 mA output drive, but rail-to-rail output and 0.45 V/µs slew rate. | Better for low-voltage (2.7 V) battery-powered apps; unsuitable for high-speed or high-current line driving. | Select when rail-to-rail output swing is critical and bandwidth <6 MHz suffices. |
| LM7332MA | Higher 20 MHz bandwidth, ±80 mA output, but no shutdown mode and higher 2.3 mA supply current. | Preferred for high-fidelity audio or active filter designs requiring faster settling and higher drive. | Select when maximum dynamic performance is prioritized over power efficiency or shutdown capability. |
Compared with OPA350UA and LM7332MA, the TLC081CDR uniquely balances 10 MHz bandwidth, ±57 mA drive, and 125 µA shutdown current in a cost-effective SOIC-8 package - making it optimal for industrial analog I/O where both performance and power management matter.

FAQ
What is the operating temperature range for the TLC081CDR?
The TLC081CDR is rated for 0°C to 70°C (commercial grade). Its "C" suffix denotes this temperature range, and it is validated per TI's SLOS254F datasheet across this span with full electrical specifications guaranteed - including 10 MHz bandwidth, ±57 mA output drive, and 125 µA shutdown current.
Does the TLC081CDR support true rail-to-rail input operation?
The TLC081CDR supports rail-to-rail common-mode input voltage from GND to VDD–2 V - meaning it accepts signals at ground potential and up to 2 V below the positive rail. It does not support input voltages at the exact VDD rail, unlike some RRO-input op-amps, but this range covers most single-supply sensor and line-driving use cases.
How is the shutdown function implemented on the TLC081CDR?
The TLC081CDR uses a dedicated SHDN pin (Pin 5) that disables the amplifier core when pulled ≤0.8 V (logic low), reducing supply current to 125 µA per channel. When pulled ≥2.0 V (logic high), full operation resumes. Turnon time is 0.47 µs and turnoff time is 2.5 µs at VDD = 12 V - enabling rapid power cycling in responsive control systems.
Can the TLC081CDR drive a 600 Ω load at 10 VPP without distortion?
Yes - the TLC081CDR delivers ±57 mA output current and exhibits 0.005% THD+N at 1 kHz, 8 VPP into 10 kΩ (per datasheet). At 600 Ω, it maintains linear operation up to ~6 VPP; for 10 VPP into 600 Ω, external current boosting or gain staging is recommended to avoid clipping or thermal derating.
What is the purpose of the NULL pins on the TLC081CDR?
The NULL pins (Pins 1 and 8) provide access to the internal offset nulling network. Connecting a 10 kΩ potentiometer between them, with the wiper to VDD or GND, allows manual trimming of input offset voltage down to <10 µV - critical for precision DC-coupled applications like weigh scales or medical sensor front ends where software calibration is impractical.
