Texas Instruments TLV9354IPWR

Overview

TLV9354IPWR from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier optimized for cost-sensitive, high-voltage systems. It delivers 3.5-MHz gain-bandwidth, ±60 mA output drive, ±350 µV input offset voltage (typ), ±1.5 µV/°C drift, and operates from 4.5 V to 40 V single supply (±2.25 V to ±20 V dual). It enables precision signal conditioning in motor drive power stages and programmable logic controllers.

For engineers reviewing the TLV9354IPWR datasheet, TLV9354IPWR pinout, TLV9354IPWR application, or TLV9354IPWR equivalent, key selection criteria include its MUX-friendly inputs (differential input range to rails), robust 110 dB CMRR, EMI/RFI-filtered inputs, low 600 µA per-amplifier quiescent current, and operation across –40°C to 125°C.

Technical Context

The TLV9354IPWR integrates four independent amplifiers sharing common supply pins, each featuring a high-slew-rate (20 V/µs) architecture with internal EMI/RFI filtering on all inputs. Its input stage supports differential voltages up to the supply rails and functions reliably in open-loop comparator mode without phase reversal.

It maintains stable performance under wide supply conditions (4.5–40 V), delivers ±60 mA output current per channel, and achieves 0.01% settling in 5 µs at 40 V supply - enabling accurate, fast response in high-voltage analog front-ends and industrial feedback loops.

FAQ

What is the maximum supply voltage for TLV9354IPWR?

The absolute maximum supply voltage for TLV9354IPWR is 42 V, with recommended operation from 4.5 V to 40 V. Exceeding 40 V risks violating absolute maximum ratings and may cause permanent damage. The device supports both single-supply (e.g., 40 V to GND) and split-supply (e.g., ±20 V) configurations, maintaining full rail-to-rail input/output functionality across this range. TLV9354IPWR's internal protection diodes clamp input signals to within 0.5 V of the rails, requiring external current limiting if inputs exceed that margin.

Does TLV9354IPWR support true rail-to-rail input operation?

Yes, TLV9354IPWR supports rail-to-rail input operation: its common-mode input voltage range extends from (V–) – 0.2 V to (V+) – 2 V, and its differential input voltage range reaches the supply rails - enabling direct connection to sensors operating at the positive or negative rail. This "MUX-friendly" behavior allows the TLV9354IPWR to function reliably in open-loop comparator mode without phase reversal, as confirmed in Figure 6-30 of the datasheet. The input stage uses complementary PMOS/NMOS pairs to achieve this extended range while maintaining low bias current (±10 pA).

Can TLV9354IPWR drive capacitive loads without instability?

TLV9354IPWR is specified to drive up to 300 pF capacitive loads while maintaining ≥60° phase margin, as verified in Figure 6-29 of the datasheet. For loads exceeding 300 pF, a series isolation resistor (RISO) of 50 Ω restores stability, as shown in Figures 6-27 and 6-28. This capability eliminates the need for external compensation networks in many test equipment and motor control applications where long traces or cable capacitance are present. TLV9354IPWR's internal compensation is optimized for unity-gain stability with moderate capacitive loading.

What is the typical quiescent current per amplifier in TLV9354IPWR?

The typical quiescent current per amplifier in TLV9354IPWR is 600 µA at 25°C and 40 V supply, with a maximum of 850 µA across –40°C to 125°C. This low IQ enables four-channel operation at <3.4 mA total, making TLV9354IPWR suitable for thermally constrained industrial modules. Quiescent current varies less than ±5% over the full 4.5–40 V supply range (Figure 6-23) and increases only ~150 µA from –40°C to 125°C (Figure 6-24), ensuring predictable power budgeting in wide-temperature deployments.

How does TLV9354IPWR handle electromagnetic interference (EMI)?

TLV9354IPWR incorporates integrated EMI/RFI filters on all input pins, achieving ≥60 dB electromagnetic interference rejection ratio (EMIRR) up to 100 MHz (Figure 6-41). This design significantly reduces sensitivity to switching noise from nearby MOSFET gate drivers, DC-DC converters, or variable-frequency drives - a critical feature in industrial motor control and PLC environments. Unlike discrete RC filtering, the on-chip filters do not degrade bandwidth or introduce phase shift, preserving the 3.5-MHz GBW and 20 V/µs slew rate while enhancing system-level EMC robustness.
