Texas Instruments TLV9064IPWT

Overview

TLV9064IPWT from Texas Instruments is a quad rail-to-rail input/output CMOS operational amplifier optimized for cost-sensitive, low-voltage systems. It delivers 10MHz unity-gain bandwidth, ±0.3mV input offset voltage, 10nV/√Hz input voltage noise, 538µA quiescent current per amplifier, and operates from 1.8V to 5.5V supply. It is used in low-side current sensing, HVAC control, and wearable device signal conditioning.

For engineers reviewing the TLV9064IPWT datasheet, TLV9064IPWT pinout, TLV9064IPWT application, or TLV9064IPWT equivalent, key selection criteria include its resistive open-loop output impedance (simplifying capacitive load stabilization), shutdown capability (1µA typical), extended temperature range (–40°C to 125°C), and compatibility with micro-size packages including TSSOP-14.

Technical Context

The TLV9064IPWT implements a CMOS input stage with ultra-low input bias current (0.5pA) and rail-to-rail input common-mode range extending 0.1V beyond both supply rails. Its unity-gain stable architecture incorporates internal RFI/EMI filtering and avoids phase reversal under overdrive conditions.

It features a resistive open-loop output impedance (~100Ω at 10MHz), enabling stable operation with higher capacitive loads than conventional op amps-critical for driving ADC inputs or long PCB traces without external compensation.

FAQ

What supply voltage range does the TLV9064IPWT support?

The TLV9064IPWT operates from a total supply voltage (V+ to V–) of 1.8V to 5.5V. This allows direct use with single-cell lithium batteries (2.7–4.2V), 3.3V logic rails, and 5V industrial supplies. The device maintains full rail-to-rail input and output swing across this entire range, and its quiescent current remains stable at 538µA per amplifier at 5.5V.

Does the TLV9064IPWT include a shutdown function?

No, the TLV9064IPWT is the standard quad op amp variant without shutdown. Shutdown functionality is exclusive to the TLV9064S family (e.g., TLV9064SRTE). The TLV9064IPWT has no SHDN pins and draws 538µA per amplifier continuously under normal operation. For low-power sleep modes, system-level power gating or selection of TLV9064S variants is required.

What is the maximum capacitive load the TLV9064IPWT can drive stably?

The TLV9064IPWT is characterized for stable operation with up to 100pF capacitive load in unity-gain configuration. Its resistive open-loop output impedance (~100Ω) significantly improves phase margin versus conventional op amps, allowing practical use with higher loads (e.g., 200–300pF) in many layouts-though full stability validation is recommended for loads exceeding 100pF per the datasheet's overshoot curves.

How does the TLV9064IPWT handle input overvoltage conditions?

The TLV9064IPWT input pins are diode-clamped to the supply rails, limiting input voltage to (V–) – 0.5V and (V+) + 0.5V. Input current is internally limited to ±10mA under overvoltage, protecting the CMOS input stage. This clamping enables robust interfacing with sensors that may transiently exceed supply rails, such as thermocouples or unregulated transducer outputs, without external protection components.

Is the TLV9064IPWT pin-compatible with other quad op amps in TSSOP-14?

The TLV9064IPWT follows the industry-standard TSSOP-14 pinout for quad op amps (e.g., IN1+, IN1–, OUT1, V+, IN2+, IN2–, OUT2, OUT3, IN3–, IN3+, V–, IN4+, IN4–, OUT4), matching pin-for-pin assignments of LM324, TLV2464, and OPA4316 in TSSOP-14. However, absolute maximum ratings, input structure (CMOS vs bipolar), and ESD protection differ-electrical validation is required before drop-in replacement.
