Texas Instruments TLC071CDGNR

Overview

TLC071CDGNR from Texas Instruments is a single-channel, wide-bandwidth (10 MHz), high-output-drive (±55 mA) BiMOS operational amplifier optimized for single-supply operation (4.5 V to 16 V). It features ultralow input offset voltage (60 µV typ), low input noise (7 nV/√Hz), and rail-to-rail output swing capability - enabling precision signal conditioning in audio line drivers, sensor front-ends, and industrial analog I/O modules.

For engineers reviewing the TLC071CDGNR datasheet, TLC071CDGNR pinout, TLC071CDGNR application, or TLC071CDGNR equivalent, this page delivers verified technical context, package-specific pin mapping, real-world application use cases, and validated alternative options - all grounded in TI's SLOS219F production data sheet and official packaging documentation.

Technical Context

The TLC071CDGNR integrates a high-impedance CMOS input stage with a bipolar output stage in TI's LBC3 BiCMOS process, delivering simultaneous high AC performance (16 V/µs slew rate, 10 MHz GBW) and robust DC accuracy (60 µV V_IO, 1.2 µV/°C drift). Its architecture supports stable unity-gain operation with load capacitances up to 100 pF and maintains phase margin ≥32° under 50-pF capacitive loading.

Designed for single-supply systems, it accepts common-mode inputs down to 0.5 V above ground and up to V_DD − 0.8 V, while offering shutdown control (SHDN pin) that reduces supply current to 125 µA per channel. The device operates across 0°C to 70°C (C-suffix) and is rated for 4.5–16 V supply range with ±2.25 V to ±8 V split-supply compatibility.

FAQ

What is the operating temperature range for the TLC071CDGNR?

The TLC071CDGNR is specified for commercial operation from 0°C to 70°C (C-suffix). 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. Thermal design should account for its 52.7°C/W junction-to-ambient thermal resistance in the MSOP PowerPAD package.

Does the TLC071CDGNR support rail-to-rail input operation?

No, the TLC071CDGNR does not support rail-to-rail input. Its common-mode input voltage range is specified from 0.5 V above GND to V_DD − 0.8 V. For example, at V_DD = 5 V, valid input voltages span 0.5 V to 4.2 V; at 12 V, the range extends to 0.5 V to 11.2 V. Input signals outside this window may cause phase reversal or increased offset error.

How does the shutdown feature of the TLC071CDGNR function?

The TLC071CDGNR has no dedicated SHDN pin - unlike TLC070, TLC073, and TLC075 variants, the TLC071CDGNR lacks integrated shutdown functionality. This is confirmed by the family package table and pinout diagrams in the SLOS219F datasheet, which show Pin 5 as NC (no connection) and omit shutdown circuitry in the TLC071 block diagram. Power-down must be implemented externally via supply switching.

What is the maximum capacitive load the TLC071CDGNR can drive stably?

The TLC071CDGNR maintains stability with capacitive loads up to 100 pF when configured as a unity-gain follower, as verified by phase margin ≥32° at 50 pF (Figure 19) and ≥37° at 100 pF (extrapolated from test data). For loads >100 pF, an isolation resistor (e.g., 20–100 Ω) in series with the output is recommended to preserve stability without degrading bandwidth significantly.

Is the TLC071CDGNR pin-compatible with the TL071CP or TL071CD?

Yes - the TLC071CDGNR shares identical functional pinout (IN−, IN+, GND, OUT, VDD) with the TL071CP (8-pin PDIP) and TL071CD (8-pin SOIC), though physical package differs (MSOP-8 vs. DIP/SOIC-8). All three use the same 8-pin configuration with Pins 1/5/8 as NC/NULL. Migration requires only PCB footprint adaptation, not schematic changes, preserving layout reuse in upgrade paths.
