Product details
Overview
TLV9351IDBVR from Texas Instruments is a single-channel, 3.5-MHz, rail-to-rail output operational amplifier optimized for cost-sensitive high-voltage systems. It delivers ±350 µV offset voltage, ±1.5 µV/°C drift, 15 nV/√Hz input noise at 1 kHz, 20 V/µs slew rate, and operates from 4.5 V to 40 V supply - enabling precision signal conditioning in motor drive power stages.
For engineers reviewing the TLV9351IDBVR datasheet, TLV9351IDBVR pinout, TLV9351IDBVR application, or TLV9351IDBVR equivalent, key selection criteria include MUX-friendly input stage (differential inputs extend to rails), robust EMI rejection, low quiescent current (600 µA), and operation across –40°C to 125°C industrial temperature range.
Technical Context
The TLV9351IDBVR integrates a high-slew-rate, low-noise amplifier core with rail-to-rail output swing and differential input voltage range extending to both supply rails. Its architecture supports open-loop comparator use and tolerates input overvoltage beyond rails when current-limited to ≤10 mA.
It features integrated EMI/RFI filters on input pins, achieves 110 dB CMRR at 25°C, and maintains stable operation driving up to 300 pF capacitive loads without external compensation - critical for sensor front-ends and feedback loops in programmable logic controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA192IDBVR | Higher precision (±5 µV offset), lower noise (5.5 nV/√Hz), but 10× higher quiescent current (1 mA vs 600 µA) | Better suited for high-resolution data acquisition; less optimal for battery-powered or thermally constrained designs | Select TLV9351IDBVR for cost-sensitive, high-voltage, low-power industrial signal chains where ±350 µV offset is acceptable |
| LM7321MAX/NOPB | Wider supply (2.7–36 V), lower GBW (20 MHz), no EMI filtering, and no rail-to-rail input capability | Lacks MUX-friendly inputs and EMI hardening - requires external protection in noisy environments | Choose TLV9351IDBVR when operating above 36 V or requiring robust EMC performance in motor drive applications |
Compared with OPA192IDBVR and LM7321MAX/NOPB, TLV9351IDBVR uniquely balances 40-V operation, rail-to-rail input tolerance, integrated EMI filtering, and sub-1-mA quiescent current - making it the preferred choice for space-constrained, high-reliability industrial analog front-ends.

FAQ
What is the maximum supply voltage rating for TLV9351IDBVR?
The absolute maximum supply voltage for TLV9351IDBVR is 42 V (V+ to V–), with recommended operation from 4.5 V to 40 V. Exceeding 42 V risks permanent damage. The device's 40-V rating supports direct integration into 24-V and 36-V industrial power rails without external regulation, and its internal protection diodes clamp input signals to within ±0.5 V of the rails when current-limited to ≤10 mA.
Does TLV9351IDBVR support true rail-to-rail input operation?
TLV9351IDBVR does not support rail-to-rail *common-mode* input - its specified common-mode range is (V–) – 0.2 V to (V+) – 2 V. However, its differential input voltage can swing up to the supply rails, enabling MUX-friendly behavior and open-loop comparator use. This distinction allows direct connection to unbuffered sources near V– while avoiding input stage saturation that occurs in conventional op amps when VCM approaches V+.
Can TLV9351IDBVR drive capacitive loads without instability?
Yes, TLV9351IDBVR is characterized to drive up to 300 pF capacitive loads while maintaining ≥60° phase margin under G = +1 conditions. Its internal compensation and low output impedance (600 Ω at 1 MHz) prevent peaking or oscillation in typical sensor buffering and DAC output configurations. For loads >300 pF, a series isolation resistor (e.g., 50 Ω) restores stability without degrading DC accuracy.
What is the operating temperature range for TLV9351IDBVR?
TLV9351IDBVR is fully specified from –40°C to +125°C ambient temperature, with electrical parameters guaranteed across this range. Thermal metrics (e.g., RθJA = 185.7°C/W for DBV package) confirm reliable operation in enclosed industrial enclosures. At 125°C, offset voltage drift remains ±1.5 µV/°C and quiescent current stays below 850 µA - ensuring consistent performance in motor drive cabinets and outdoor PLC housings.
How does the EMI/RFI filtering in TLV9351IDBVR improve system-level immunity?
TLV9351IDBVR integrates on-die EMI/RFI filters on both input pins, providing >40 dB rejection at 100 MHz as measured by EMIRR. This hardens the amplifier against radiated noise from switching power supplies, IGBT gate drivers, and RF transceivers - reducing susceptibility-induced offset shifts and false triggering in safety-critical monitoring circuits. Unlike external RC filters, this solution preserves bandwidth and avoids phase lag in closed-loop control paths.
