Texas Instruments TLV2772ACD

Overview

TLV2772ACD from Texas Instruments is a dual-channel, rail-to-rail output CMOS operational amplifier optimized for precision, low-voltage, and low-power applications. It delivers 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, 360 µV input offset voltage, 17 nV/√Hz input noise, and 1 mA per-channel supply current across 2.5 V to 5.5 V operation - enabling high-fidelity signal conditioning in portable medical sensors and automotive body control modules.

For engineers reviewing the TLV2772ACD datasheet, TLV2772ACD pinout, TLV2772ACD application, or TLV2772ACD equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail output drive into 600 Ω with 0.005% THD+N, temperature-stable performance from −40°C to 125°C, and validated alternatives for ADC driver and sensor interface designs.

Technical Context

The TLV2772ACD employs a CMOS input stage with 2 pA input bias current and 10¹² Ω differential input resistance, supporting high-impedance sensor interfacing. Its unity-gain-stable architecture achieves 46° phase margin with 600 Ω load and 100 pF capacitance, ensuring robust stability in active filter and transimpedance configurations.

It integrates micropower shutdown mode (IDD < 1.5 µA) with defined turnon/turnoff thresholds (V(ON) = 1.40 V, V(OFF) = 1.20 V at 2.7 V), enabling precise power gating in battery-operated systems without external logic. The device is characterized across extended temperature ranges and supports single-supply operation down to 2.5 V.

Key Specifications

Pinout & Package

TLV2772ACD is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package, compliant with JEDEC MS-012, with 1.27 mm pitch and standard surface-mount footprint. Thermal resistance θJA = 150°C/W enables operation at full rating without forced airflow.

FAQ

What is the maximum operating supply voltage for TLV2772ACD?

The absolute maximum supply voltage for TLV2772ACD is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage, while operation below 2.5 V may cause degraded gain-bandwidth and increased input offset voltage. TI specifies full electrical performance only within the 2.5–5.5 V window, and TLV2772ACD must be used within this range for guaranteed functionality in production designs.

Does TLV2772ACD support true rail-to-rail input?

No, TLV2772ACD features rail-to-rail *output* only. Its common-mode input voltage range extends from GND to VDD −1.3 V (at 2.7 V supply), meaning the inputs cannot accept signals within 1.3 V of VDD. This limitation is explicitly documented in the "Recommended Operating Conditions" table of the TLV2772ACD datasheet - unlike rail-to-rail input op-amps, TLV2772ACD requires careful input biasing to remain within its valid VIC range.

Is TLV2772ACD pin-compatible with other devices in the TLV277x family?

Yes, TLV2772ACD shares identical SOIC-8 pinout with TLV2772CD, TLV2772ID, and TLV2772AID - all variants use Pins 1–3 (Ch1), 4 (GND), 5–7 (Ch2), and 8 (VDD). However, TLV2772ACD is not pin-compatible with TLV2771 (SOT-23-5) or TLV2774 (SOIC-14); the "A" suffix denotes tighter initial offset (1.6 mV max) and extended temperature grade, but does not affect pin assignment.

What is the typical THD+N performance of TLV2772ACD at 1 kHz?

TLV2772ACD achieves 0.005% THD+N at 1 kHz when driving a 600 Ω load with AV = 1, as measured at VDD = 5 V. This value is confirmed in the "Operating Characteristics" table (page 9) of the official SLOS209G datasheet. Performance degrades to 0.016% at AV = 10 and 0.095% at AV = 100 - confirming that TLV2772ACD is optimized for unity-gain or low-gain line-driving applications, not high-gain small-signal amplification.

How does the shutdown feature of TLV2772ACD function?

TLV2772ACD does not include an integrated shutdown pin - the "A" suffix refers to enhanced initial offset and temperature grade, not shutdown capability. Only TLV2770, TLV2773, and TLV2775 variants in the TLV277x family offer shutdown functionality. TLV2772ACD draws 1 mA per channel continuously; any power-gating must be implemented externally via VDD switching or enable circuitry. This is clearly stated in the "Family Package Table" and absence of SHDN pin in the SOIC-8 pinout diagram.
