Product details
Overview
TLV9354IDYYR 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, 20 V/µs slew rate, ±350 µV max input offset voltage, and operates from 4.5 V to 40 V single-supply (or ±2.25 V to ±20 V dual-supply), enabling use in motor drive power stages and programmable logic controllers.
For engineers reviewing the TLV9354IDYYR datasheet, TLV9354IDYYR pinout, TLV9354IDYYR application, or TLV9354IDYYR equivalent, key selection criteria include its MUX-friendly inputs (differential input range to supply rails), robust 110 dB CMRR, low 600 µA per-amplifier quiescent current, and EMI/RFI-filtered inputs for noisy industrial environments.
Technical Context
The TLV9354IDYYR implements a precision bipolar-input op-amp architecture with integrated EMI filtering on all input pins and rail-to-rail output stage capable of sourcing/sinking ±60 mA. Its differential input voltage range extends to the supply rails, supporting open-loop comparator operation without external clamping.
It features a stable unity-gain compensated design (60° phase margin), drives up to 300 pF capacitive loads, and maintains 120 dB open-loop gain across –40°C to 125°C, making it suitable for closed-loop servo control where DC accuracy and AC fidelity must coexist under wide supply and temperature variation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 3.5 MHz - supports stable unity-gain buffer and gain-of-10 amplification up to 350 kHz |
| Slew rate | 20 V/µs - enables clean 10-V step response in ≤500 ns with minimal distortion |
| Input offset voltage | ±0.35 mV (max) - ensures <1 mV error in 12-bit ADC front-end applications at room temperature |
| Supply voltage range | 4.5 V to 40 V (single) - powers directly from industrial 24-V rails or wide-range DC-DC outputs |
| Quiescent current | 650–800 µA per amplifier - allows four-channel operation below 3.2 mA total, critical for thermally constrained modules |
| Common-mode rejection | 110 dB (typ) - rejects >100,000:1 of common-mode noise in motor current sensing |
| Output drive | ±60 mA - drives 2-kΩ loads to rail with <250 mV headroom at 40 V supply |
Pinout & Package
SOT-23-14 (DYY) package: 4.20 mm × 1.90 mm body, 0.65 mm pitch, surface-mount, thermally enhanced for quad-channel density in space-constrained designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, channel A | Accepts signals up to V– – 0.2 V and V+ – 2 V; compatible with rail-to-rail sensor outputs |
| –IN A (Pin 2) | Inverting input, channel A | Differential input range extends to supply rails; usable as comparator input without external biasing |
| OUT A (Pin 1) | Output, channel A | Rail-to-rail swing; sinks/sources ±60 mA; requires no external pull-up/down for digital interface emulation |

| V– (Pin 11) | Negative supply | Lowest potential node; may be ground (single-supply) or negative rail (dual-supply); connects to PCB ground plane |
| +IN B (Pin 5), –IN B (Pin 6), OUT B (Pin 7) | Channel B inputs/outputs | Electrically identical to channel A; independent operation enables multi-signal conditioning in one footprint |
| +IN C (Pin 10), –IN C (Pin 9), OUT C (Pin 8) | Channel C inputs/outputs | Same specs as A/B; supports three-phase motor current monitoring with matched DC performance |
| +IN D (Pin 12), –IN D (Pin 13), OUT D (Pin 14) | Channel D inputs/outputs | Enables fourth independent signal path-e.g., fault detection, reference buffer, or auxiliary feedback loop |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4197IPWR | Lower offset (±5 µV), higher GBW (10 MHz), but 1.1 mA per amplifier quiescent current and no MUX-friendly inputs | Better for precision instrumentation; less suitable for cost-sensitive, low-power, rail-swing-critical motor control | Choose TLV9354IDYYR when supply current <3.2 mA and rail-to-rail input capability are mandatory |
| LM324DR | Legacy quad op-amp; 700 kHz GBW, ±3 mV offset, no rail-to-rail output, no EMI filtering | Acceptable for basic signal buffering where accuracy and noise immunity are secondary | TLV9354IDYYR replaces LM324DR where 3.5-MHz bandwidth, 20 V/µs slew, and industrial-grade EMI rejection are required |
Compared with OPA4197IPWR and LM324DR, TLV9354IDYYR uniquely balances cost, 40-V operation, rail-to-rail input/output, low quiescent current, and built-in EMI filtering-making it optimal for next-generation motor drives and PLC analog I/O where performance and robustness must coexist within tight BOM constraints.

FAQ
What is the maximum supply voltage rating for TLV9354IDYYR?
The absolute maximum supply voltage for TLV9354IDYYR is 42 V between V+ and V– terminals. The recommended operating range is 4.5 V to 40 V (single-supply) or ±2.25 V to ±20 V (dual-supply). Operation beyond 40 V is not guaranteed and risks permanent damage. All electrical specifications in the TLV9354IDYYR datasheet are validated within the 4.5–40 V range.
Does TLV9354IDYYR support true rail-to-rail input operation?
Yes, TLV9354IDYYR supports rail-to-rail differential input voltage range: inputs tolerate common-mode voltages from (V–) – 0.2 V to (V+) – 2 V. This enables direct connection to sensors or multiplexers operating at the supply rails without external level-shifting circuitry-confirmed in Section 6.7 of the TLV9354IDYYR datasheet under "Input Voltage Range" and "MUX-friendly/comparator inputs" feature.
Can TLV9354IDYYR be used as a comparator?
Yes, TLV9354IDYYR can operate open-loop as a comparator due to its MUX-friendly inputs and rail-to-rail output. Its differential input range extends to supply rails, and output swings fully to both rails. However, it lacks internal hysteresis and propagation delay optimization-so external hysteresis is recommended for noise immunity. This capability is explicitly documented in the "MUX-friendly/comparator inputs" feature list of the TLV9354IDYYR datasheet.
What is the thermal resistance (RθJA) of TLV9354IDYYR in the SOT-23-14 (DYY) package?
The junction-to-ambient thermal resistance (RθJA) for TLV9354IDYYR in the SOT-23-14 (DYY) package is 110.6 °C/W, as specified in Section 6.6 ("Thermal Information for Quad Channel") of the TLV9354IDYYR datasheet. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves with PCB copper pour and thermal vias.
Is TLV9354IDYYR qualified for automotive applications?
No, TLV9354IDYYR is not AEC-Q100 qualified. It is specified for industrial operation from –40°C to +125°C ambient temperature, but lacks automotive-specific qualification, stress testing, or failure-rate reporting. For automotive use, TI recommends alternatives such as the OPA4197-Q1 or TLV9304-Q1. The TLV9354IDYYR datasheet explicitly states its intended use in "cost-sensitive systems" including PLCs and motor drives-not automotive safety-critical subsystems.
