Product details
Overview
TLV9352IDR from Texas Instruments is a dual-channel, 3.5-MHz, 40-V rail-to-rail output operational amplifier optimized for cost-sensitive industrial and motor control systems. It delivers ±350 µV offset voltage, ±1.5 µV/°C drift, 15 nV/√Hz input noise at 1 kHz, 110 dB CMRR, and 20 V/µs slew rate - enabling precision signal conditioning in AC servo drives and programmable logic controllers.
For engineers reviewing the TLV9352IDR datasheet, TLV9352IDR pinout, TLV9352IDR application, or TLV9352IDR equivalent, this page provides verified specifications, SOIC-8 package layout, MUX-friendly input behavior, robust EMI rejection (EMIRR), and validated alternatives for high-voltage analog front-ends requiring stable DC accuracy and fast transient response.
Technical Context
The TLV9352IDR integrates two independent amplifiers with differential input voltage range extending to both supply rails - allowing operation as a comparator or open-loop buffer without phase reversal. Its internal architecture supports rail-to-rail output swing down to 5 mV from rails (at no load, VS = 40 V) and delivers ±60 mA short-circuit current per channel.
Designed for wide-supply operation (±2.25 V to ±20 V or 4.5 V to 40 V), it features integrated EMI/RFI filters on input pins, 600 µA per amplifier quiescent current, and stable unity-gain performance with up to 300 pF capacitive load - making it suitable for noisy industrial environments and multiplexed sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 3.5 MHz - supports stable closed-loop gain up to ~35 at 100 kHz for precision filtering or signal amplification |
| Slew rate | 20 V/µs - enables accurate reproduction of fast transients in motor current sensing or encoder signal conditioning |
| Input offset voltage | ±0.35 mV (typ) - ensures <1 LSB error in 12-bit ADC interfaces with gain ≥10 |
| Common-mode rejection | 110 dB (typ) - suppresses power supply ripple and ground noise in single-supply industrial I/O modules |
| Supply voltage range | 4.5 V to 40 V - compatible with 24-V industrial bus and 36-V motor drive auxiliary rails |
| Quiescent current | 650 µA per amplifier (max) - enables low-power operation in always-on PLC analog inputs |
| Output swing headroom | 5 mV from rail (no load, VS = 40 V) - maximizes dynamic range in high-side current sensing with shunt resistors |
Pinout & Package
TLV9352IDR is housed in an 8-pin SOIC (D) package measuring 4.90 mm × 3.90 mm, rated for operation from –40°C to +125°C. The package supports standard surface-mount reflow profiles and offers thermal resistance RθJA = 138.7°C/W.
| 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; supports rail-to-rail common-mode range |
| –IN A (Pin 2) | Inverting input, Channel A | Differential input voltage may extend to supply rails; usable in comparator mode without external clamping |
| OUT A (Pin 1) | Output, Channel A | Rail-to-rail capable; drives loads down to 2 kΩ while maintaining <250 mV headroom at VS = 40 V |
| V– (Pin 4) | Negative supply | Reference for both channels; accepts ground or negative rail; input common-mode extends 0.2 V below V– |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent of Channel A; identical electrical specs enable dual-sensor signal conditioning |
| –IN B (Pin 6) | Inverting input, Channel B | Supports MUX-friendly operation: no phase reversal when inputs exceed supply rails |
| OUT B (Pin 7) | Output, Channel B | Delivers ±60 mA short-circuit current; maintains stability with 300 pF capacitive load |
| V+ (Pin 8) | Positive supply | Maximum 40 V; supplies both amplifiers; PSRR >95 dB minimizes supply noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| MUX-friendly/comparator inputs | Operates linearly with differential inputs beyond supply rails; eliminates need for external clamping diodes in multiplexed sensor arrays |
| Rail-to-rail output | Swings within 5 mV of supply rails under no-load conditions, maximizing signal fidelity in single-supply data acquisition |
| Robust EMIRR performance | Integrated EMI/RFI filters reject >60 dB interference at 100 MHz - critical for motor drive PCBs near IGBT switching noise |
| Low input bias current | ±10 pA (max) enables high-impedance source interfacing (e.g., thermocouples, pH electrodes) without significant offset error |
| Wide temperature range | Specified from –40°C to +125°C - qualified for under-hood automotive subsystems and industrial enclosures without derating |
Applications
| AC Motor Drive Power Stage | Programmable Logic Controller (PLC) Analog Input |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2991IDR | Lower offset (±125 µV), higher GBW (4.5 MHz), but higher IQ (1.1 mA per amp); no integrated EMI filters | Better for ultra-low-offset precision instrumentation; less suited for noisy motor drive environments | Select when offset drift and bandwidth outweigh EMI immunity and quiescent power requirements |
| LM358BDR | Lower cost, lower performance: ±3 mV offset, 700 kHz GBW, no rail-to-rail output, no EMI filtering | Acceptable for non-critical DC-coupled amplification where cost dominates over accuracy and noise | Choose only for legacy designs or cost-constrained consumer-grade equipment with relaxed spec margins |
Compared with OPA2991IDR and LM358BDR, TLV9352IDR uniquely balances 3.5-MHz bandwidth, ±350 µV offset, rail-to-rail output, and built-in EMI rejection - making it optimal for industrial motor control where signal integrity and reliability coexist under electromagnetic stress.

FAQ
What is the maximum supply voltage for TLV9352IDR?
The TLV9352IDR supports a maximum supply voltage of 40 V (or ±20 V). Absolute maximum ratings specify 42 V across V+ and V–, but recommended operating conditions limit continuous use to 40 V to ensure long-term reliability and specified performance across –40°C to +125°C. Exceeding 40 V may degrade offset drift and CMRR.
Does TLV9352IDR support true rail-to-rail input operation?
TLV9352IDR supports rail-to-rail *output* swing, but its input common-mode range extends from (V–) – 0.2 V to (V+) – 2 V - not full rail-to-rail. However, its differential input voltage can reach the supply rails, enabling MUX-friendly and comparator-like operation without phase reversal, which is functionally distinct from classic rail-to-rail input op-amps.
Can TLV9352IDR be used as a comparator?
Yes, TLV9352IDR is explicitly designed for open-loop comparator use due to its MUX-friendly inputs: it operates linearly with differential inputs up to the supply rails and exhibits no phase reversal. However, it lacks dedicated comparator features like internal hysteresis or push-pull output - external hysteresis is recommended for clean switching in noisy environments.
What is the thermal resistance (RθJA) of TLV9352IDR in SOIC-8 package?
The TLV9352IDR in SOIC-8 (D) package has a junction-to-ambient thermal resistance (RθJA) of 138.7°C/W under standard JEDEC 2-layer board conditions. This value assumes proper PCB copper pour and via placement; actual thermal performance improves with enhanced heatsinking or multi-layer layouts with internal ground planes.
Is TLV9352IDR suitable for automotive applications?
TLV9352IDR is qualified for operation from –40°C to +125°C and features robust EMI rejection, making it suitable for under-hood automotive subsystems such as motor control units and battery management sensor interfaces. While not AEC-Q100 certified, its parametric performance and temperature rating align with many non-safety-critical automotive use cases.
