Product details
Overview
TLV9354IDR from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier optimized for cost-sensitive, high-voltage industrial systems. It delivers 3.5-MHz gain-bandwidth, ±60 mA output drive, ±350 µV max input offset voltage, and operates from 4.5 V to 40 V supply - enabling precision signal conditioning in AC motor drive power stages and PLC analog I/O modules.
For engineers reviewing the TLV9354IDR datasheet, TLV9354IDR pinout, TLV9354IDR application, or TLV9354IDR equivalent, this page provides verified specifications, SOIC-14 package details, MUX-friendly input behavior, EMI-hardened performance, and validated alternative options for high-voltage op amp selection.
Technical Context
The TLV9354IDR integrates four independent amplifiers with differential input voltage range extending to both supply rails, supporting open-loop comparator operation without external clamping. Its robust 20 V/µs slew rate and 600 µA per amplifier quiescent current balance speed and efficiency across wide supply (±2.25 V to ±20 V) and temperature (–40°C to 125°C) ranges.
EMI/RFI filtering on all inputs ensures stable operation in noisy industrial environments, while rail-to-rail output swing (as low as 5 mV from rail at no load, 50 mV at 10 kΩ) supports full-scale ADC interfacing. The device's 110 dB CMRR and 15 nV/√Hz input voltage noise at 1 kHz support precision DC-coupled sensing and closed-loop control loops.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4197IPW | Lower offset (±5 µV typ), higher GBW (10 MHz), but higher IQ (1 mA/ch) and narrower supply (4.5–36 V) | Better DC precision and bandwidth; less suitable for ultra-low-power or 40-V rail systems | Select when sub-µV offset and >5-MHz closed-loop bandwidth are required; verify thermal design for higher IQ |
| LM324DR | Lower cost, wider temp range (–40°C to 125°C), but lower GBW (1.2 MHz), higher offset (±3 mV), no rail-to-rail output | Acceptable for non-critical DC amplification where headroom >1.5 V is available | Select only for cost-driven, non-precision applications with relaxed accuracy and speed requirements |
Compared with TLV9354IDR, OPA4197IPW offers superior DC accuracy and bandwidth at higher power and reduced voltage margin, while LM324DR trades performance for cost and legacy compatibility - making TLV9354IDR the optimal balance of precision, speed, supply flexibility, and industrial ruggedness.

FAQ
What is the maximum supply voltage rating for TLV9354IDR?
The TLV9354IDR has an absolute maximum supply voltage (VS = V+ – V−) of 42 V, with recommended operation from 4.5 V to 40 V. This allows direct use with standard 24-V industrial rails and ±15-V analog systems. Exceeding 42 V risks permanent damage, as specified in Section 6.1 of the SBOS994E datasheet. The TLV9354IDR maintains full functionality across this entire range.
Does TLV9354IDR support true rail-to-rail input operation?
TLV9354IDR supports rail-to-rail *output* swing but not full rail-to-rail *input* common-mode range. Its input common-mode voltage range is specified as (V−) – 0.2 V to (V+) – 2 V - meaning the positive input can approach V− closely but cannot reach V+. However, its differential input voltage range extends to the supply rails, enabling MUX-friendly operation and open-loop comparator use without external clamping, as confirmed in Section 1 and Table 5-3 of the datasheet.
Can TLV9354IDR be used as a comparator?
Yes, TLV9354IDR is explicitly designed for comparator use in open-loop configurations. Its MUX-friendly inputs tolerate differential voltages up to the supply rails, and it exhibits no phase reversal (Figure 6-30). While not a dedicated comparator, it supports reliable overdrive recovery (<600 ns) and stable saturation - making it suitable for low-speed, cost-sensitive comparator functions in PLC I/O or fault-detection circuits where TLV9354IDR's precision and rail-to-rail output add value.
What is the thermal resistance (RθJA) of TLV9354IDR in SOIC-14 package?
The junction-to-ambient thermal resistance (RθJA) for TLV9354IDR in the SOIC-14 (D) package is 101.2°C/W, as measured on a standard JEDEC 2S2P board per Section 6.6 of the SBOS994E datasheet. This value assumes standard PCB layout with 2 oz copper and two internal planes. Derating is required above 125°C ambient; maximum junction temperature remains 150°C per absolute ratings.
Is TLV9354IDR qualified for automotive applications?
No, TLV9354IDR is not AEC-Q200 qualified. It is specified for industrial operation from –40°C to 125°C and carries no automotive qualification. While its temperature range overlaps with some automotive grades, TI positions the TLV935x family exclusively for industrial, test & measurement, and cost-sensitive high-voltage applications - not automotive safety-critical systems. For automotive use, consider TI's TLV9304-Q1 or OPA4197-Q1 variants instead of TLV9354IDR.
