Product details
Overview
TLC081CDGN from Texas Instruments is a single-channel BiMOS operational amplifier optimized for wide-bandwidth, high-output-drive single-supply applications. 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 TLC081CDGN datasheet, TLC081CDGN pinout, TLC081CDGN application, or TLC081CDGN equivalent, key selection criteria include its rail-to-rail input capability (VICR = GND to VDD–2 V), ultralow 125 µA shutdown current per channel, and MSOP-8 PowerPAD™ package for thermal performance in space-constrained designs.
Technical Context
The TLC081CDGN employs a CMOS front end with bipolar output stage, combining >1 GΩ differential input resistance and 8.5 nV/√Hz input voltage noise with ±57 mA sourcing/sinking capability. Its architecture supports stable unity-gain operation with ≥32° phase margin at 50 pF load.
It features an integrated shutdown pin (SHDN) referenced to GND, requiring ≤0.8 V for disable and ≥2 V for enable, with turnoff time of 1.3 µs and turnon time of 0.15 µs at 25°C - suitable for power-gated analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10 MHz - enables accurate amplification of signals up to audio and low-speed communication frequencies. |
| Output Drive | ±57 mA - drives heavy loads such as 600 Ω audio lines or multiple logic inputs without external buffers. |
| Slew Rate | +16 V/µs / –19 V/µs - supports fast transient response in pulse amplification and active filter stages. |
| Supply Range | 4.5 V to 16 V - compatible with single Li-ion, 5 V, 12 V, and automotive battery-supplied systems. |
| Input Offset | 60 µV (typ) - ensures high DC precision in sensor front ends and precision instrumentation. |
| Shutdown Current | 125 µA/channel - reduces system standby power in battery-operated devices with periodic analog sensing. |

Pinout & Package
Package: MSOP-8 PowerPAD™ (DGN), thermally enhanced 3 mm × 3 mm body with exposed thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NULL) | No internal connection | Unused pin; must be left floating or tied to GND for mechanical stability only. |

| 5 (SHDN) | Shutdown control input | CMOS-compatible logic input; ≤0.8 V disables amplifier, ≥2 V enables; no pull-up required. |
| 6 (VDD) | Positive supply | Single supply rail (4.5–16 V); powers both input and output stages; decoupling near pin critical. |
| 7 (OUT) | Amplifier output | Class-AB bipolar output stage capable of ±57 mA into resistive or capacitive loads. |
| 8 (NULL) | No internal connection | Unused pin; same mechanical role as Pin 1 - no electrical function. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2461CDGN | Lower bandwidth (6.4 MHz), lower output drive (±15 mA), rail-to-rail output only (not input). | Not suitable for high-current line driving; better for low-voltage (2.7 V) battery systems. | Select when supply is <5 V and output loading is light; avoid for 600 Ω audio or industrial actuator interfaces. |
| OPA2340UA/2K5 | Higher precision (50 µV max VIO), lower noise (7 nV/√Hz), but limited output drive (±20 mA) and narrower supply (2.7–5.5 V). | Optimized for low-voltage precision instrumentation, not high-drive or wide-supply applications. | Choose for sub-5 V, ultra-low-offset sensor signal chains; reject for 12 V systems or >±30 mA loads. |
Compared with TLV2461CDGN and OPA2340UA/2K5, the TLC081CDGN uniquely balances 10 MHz bandwidth, ±57 mA drive, and 4.5–16 V operation - making it the only option among the three capable of driving 600 Ω loads from a 12 V rail while maintaining audio-grade distortion performance.

FAQ
What is the operating temperature range for the TLC081CDGN?
The TLC081CDGN is rated for 0°C to 70°C (commercial grade). Its absolute maximum junction temperature is 150°C, and it is qualified per TI's standard reliability testing for continuous operation within this ambient range. The "C" suffix explicitly denotes the commercial temperature grade, distinct from the "I" (–40°C to 125°C) variant.
Does the TLC081CDGN support rail-to-rail input?
Yes, the TLC081CDGN supports rail-to-rail input with a common-mode input voltage range (VICR) from GND to VDD–2 V. This allows direct interfacing with zero-referenced sensors and DACs without level-shifting circuitry - confirmed in the Recommended Operating Conditions table of the SLOS254F datasheet.
What is the purpose of Pins 1 and 8 on the TLC081CDGN MSOP-8 package?
Pins 1 and 8 of the TLC081CDGN are labeled NULL in the datasheet pin diagram and have no internal connection. They serve mechanical and thermal roles only - providing structural symmetry and aiding solder joint reliability. Neither pin carries electrical functionality and must not be used as grounds or ties unless specified in layout guidelines for thermal pad anchoring.
How does the shutdown feature of the TLC081CDGN behave electrically?
The TLC081CDGN shutdown pin (Pin 5) is a CMOS-input logic control: asserting ≤0.8 V disables the amplifier (reducing IDD to 125 µA/channel), while ≥2 V enables normal operation. The transition times are 0.15 µs (turnon) and 1.3 µs (turnoff) at 25°C - defined by supply current reaching 50% of final value, per the Electrical Characteristics table.
Can the TLC081CDGN drive a 600 Ω load at 12 V supply?
Yes, the TLC081CDGN can drive a 600 Ω load at 12 V supply. At VDD = 12 V and TA = 25°C, VOH = 10.3 V (min) at IOH = –50 mA and VOL = 0.65 V (max) at IOL = 50 mA - confirming full swing into 600 Ω (20 mA @ 12 V) with >10 VPP output capability and <0.022% THD+N at 1 kHz, as verified in the Electrical Characteristics tables.
