Texas Instruments TLV2775IPW

Overview

TLV2775IPW from Texas Instruments is a quad CMOS operational amplifier with rail-to-rail output, 5.1 MHz gain-bandwidth product, 10.5 V/µs slew rate, and micropower shutdown mode (IDD < 1 µA per channel). It operates from 2.5 V to 5.5 V single supply and delivers low distortion (0.005% THD+N into 600 Ω) for precision analog front-end conditioning in automotive sensor interfaces.

For engineers reviewing the TLV2775IPW datasheet, TLV2775IPW pinout, TLV2775IPW application, or TLV2775IPW equivalent, this device is selected for high-speed, low-power, rail-to-rail signal conditioning where input offset voltage (360 µV max), noise (17 nV/√Hz), and wide temperature range (−40°C to 125°C) are critical design constraints.

Technical Context

The TLV2775IPW integrates four independent high-slew-rate amplifiers in a single TSSOP-16 package, each featuring CMOS input stage with 2 pA bias current and rail-to-rail output swing. Its architecture supports unity-gain stable operation with 46° phase margin at 600 Ω load and 100 pF capacitance.

It includes dedicated shutdown control pins (1/2SHDN and 3/4SHDN) enabling independent power gating of amplifier pairs, reducing total quiescent current to sub-microamp levels while preserving fast turnon/turnoff times (1.9 µs / 345 ns typical).

FAQ

What is the maximum operating supply voltage for TLV2775IPW?

The absolute maximum supply voltage for TLV2775IPW is 7 V, but the recommended operating range is 2.5 V to 5.5 V. Operation above 5.5 V risks permanent damage and violates TI's specified conditions; designs using 5 V rails achieve optimal THD+N (0.005%) and output drive capability while maintaining 1 mA per channel supply current.

Does TLV2775IPW support true rail-to-rail input?

No, TLV2775IPW features rail-to-rail *output* only. Its common-mode input voltage range extends from GND to VDD − 1.3 V (at VDD = 5 V), meaning the inputs cannot accept signals within 1.3 V of VDD. This limitation requires careful biasing in single-supply configurations - for example, setting input common-mode at VDD/2 via resistive dividers when interfacing with AC-coupled sensors.

How does the shutdown function work on TLV2775IPW?

The TLV2775IPW uses a single logic-compatible shutdown pin (Pin 16) that controls both amplifier pairs: pulling Pin 16 low enables all four amplifiers; pulling it high disables Amplifiers A/B and C/D simultaneously. In shutdown, supply current drops to <1.5 µA per channel, and outputs enter high-impedance state - requiring external pull-downs if bus contention must be avoided in multiplexed systems.

Can TLV2775IPW drive a 10-kΩ load with rail-to-rail output swing?

Yes, TLV2775IPW maintains rail-to-rail output swing (within 10 mV of rails) when driving 10-kΩ loads at room temperature and 5 V supply. However, output swing degrades under heavier loads: at 2.2 mA (e.g., 2.2 kΩ), VOH drops to 4.4 V and VOL rises to 0.6 V. For full rail-to-rail fidelity, keep load impedance ≥10 kΩ or reduce gain to limit output current demand.

Is TLV2775IPW qualified for automotive applications?

Yes, the TLV2775IPW is offered in the I-suffix grade (TLV2775ID / TLV2775IPW), qualified per AEC-Q100 Grade 2 (−40°C to 105°C ambient) and tested across −40°C to 125°C junction temperature. Its 360 µV offset stability, 93 dB CMRR, and robust ESD protection (2-kV HBM) meet requirements for engine control, battery monitoring, and ADAS sensor signal chains.
