Product details
Overview
TLV9352IDDFR from Texas Instruments is a dual-channel, 3.5-MHz, rail-to-rail output operational amplifier optimized for cost-sensitive high-voltage systems. It delivers ±350 µV max input offset voltage, ±1.5 µV/°C drift, 15 nV/√Hz input voltage noise at 1 kHz, 20 V/µs slew rate, and operates from 4.5 V to 40 V supply. It serves in motor drive servo control modules where precision, robustness, and MUX-friendly input stage operation are required.
For engineers reviewing the TLV9352IDDFR datasheet, TLV9352IDDFR pinout, TLV9352IDDFR application, or TLV9352IDDFR equivalent, this page provides verified specifications, dual-channel pin mapping for SOT-23-8 package, real-world use cases in industrial automation, and validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLV9352IDDFR implements a dual-channel CMOS input stage with differential input voltage range extending to both supply rails-enabling true MUX-friendly operation and open-loop comparator use without phase reversal. Its architecture supports rail-to-rail output swing with ±60 mA short-circuit current capability and maintains 110 dB common-mode rejection across –40°C to 125°C.
It features integrated EMI/RFI filters on input pins, delivering >80 dB EMIRR up to 1 GHz, and sustains stable unity-gain operation with capacitive loads up to 300 pF. The device's 3.5-MHz gain-bandwidth product and 60° phase margin ensure predictable settling (4 µs to 0.1%) in high-speed feedback loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 4.5 V to 40 V (±2.25 V to ±20 V): Supports single-supply industrial sensors and dual-supply analog front-ends without level-shifting. |
| Gain-Bandwidth Product | 3.5 MHz: Enables stable closed-loop gain ≥10 at ≥350 kHz for anti-aliasing or signal conditioning stages. |
| Slew Rate | 20 V/µs: Supports 10-V step response within 500 ns-critical for fast-settling current-sense amplifiers in motor drives. |
| Input Offset Voltage | ±0.35 mV (max): Ensures ≤3.5 mV error in 10× gain configurations-vital for sub-1% accuracy in PLC analog I/O modules. |
| Input Bias Current | ±10 pA (max): Minimizes voltage error across high-impedance source networks (e.g., thermocouple or RTD interfaces). |
| Output Drive | ±60 mA short-circuit current: Directly drives 100-Ω loads or low-side gate resistors without external buffers. |
| EMI Rejection | EMIRR >80 dB up to 1 GHz: Suppresses RF interference from switching power supplies or motor commutation noise. |
Pinout & Package
TLV9352IDDFR is housed in an 8-pin SOT-23 package (body size 1.60 mm × 2.90 mm), optimized for space-constrained PCB layouts in motor control and PLC modules.
| 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; enables direct connection to multiplexer outputs or sensor bridges. |
| –IN A (Pin 2) | Inverting input, Channel A | Differential input range extends to supply rails-supports comparator mode with no external clamping diodes. |
| OUT A (Pin 1) | Output, Channel A | Rail-to-rail swing with ≤55 mV headroom at 10 kΩ load; drives ADC reference buffers or PWM modulator inputs. |
| V– (Pin 4) | Negative power supply | Low-impedance return path; must be decoupled with 100 nF ceramic capacitor near package for stability. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent channel for dual-loop control (e.g., current + velocity loop) or redundant sensing paths. |
| –IN B (Pin 6) | Inverting input, Channel B | Same rail-to-rail input tolerance as Channel A-enables matched differential pair configurations. |
| OUT B (Pin 7) | Output, Channel B | Simultaneous dual-output operation with <5 µs settling to 0.01%; suitable for stereo audio or dual-axis position feedback. |
| V+ (Pin 8) | Positive power supply | Supports up to 40 V-allows direct interface with 24-V industrial bus without external regulators. |
Key Features
| Feature | Design Value |
|---|---|
| MUX-friendly inputs | Differential input voltage range extends to supply rails-eliminates need for external clamp diodes when used after analog multiplexers. |
| Rail-to-rail output | Delivers full 39.9 Vpp swing from 40-V supply at 10-kΩ load-maximizes dynamic range in high-voltage data acquisition. |
| High EMI immunity | Integrated EMI/RFI filters suppress >80 dB of 100-MHz–1-GHz noise-reduces layout sensitivity in noisy motor drive environments. |
| Low quiescent current | 650 µA per amplifier at 25°C-enables always-on monitoring circuits in battery-backed industrial controllers. |
| No phase reversal | Guaranteed non-inverting behavior even when inputs exceed supply rails-prevents latch-up in overvoltage fault conditions. |
| Robust thermal performance | RθJA = 143.5°C/W in SOT-23-8 package-supports continuous operation at 125°C ambient with minimal derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, high-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2182IDR | Lower offset (±4 µV), higher precision, but 10-MHz GBW and 2.5-mA IQ; requires ±18 V max supply. | Better for metrology-grade instrumentation; not rated for 40-V operation or industrial temperature range. | Select when sub-0.01% accuracy is mandatory and supply is ≤36 V; avoid for 40-V motor drive rails. |
| LM2904BQDR | Lower cost, 700-kHz GBW, ±3-mV offset, 36-V max supply, no rail-to-rail output. | Suitable for basic signal buffering in 24-V PLCs but lacks MUX-friendliness and EMI filtering. | Choose for cost-driven legacy designs where speed and precision are secondary; verify output swing meets load requirements. |
Compared with TLV9352IDDFR, OPA2182IDR trades higher precision and bandwidth for reduced supply voltage range and increased power consumption, while LM2904BQDR offers lower cost at the expense of speed, noise, and rail-to-rail capability-making TLV9352IDDFR optimal for 40-V, noise-sensitive, space-constrained industrial control.

FAQ
What is the maximum supply voltage for TLV9352IDDFR?
The absolute maximum supply voltage for TLV9352IDDFR is 42 V, but the recommended operating range is 4.5 V to 40 V. Operating at 40 V enables direct interfacing with 24-V and 36-V industrial buses without regulation, while maintaining full specification compliance across –40°C to 125°C.
Does TLV9352IDDFR support true rail-to-rail input operation?
TLV9352IDDFR supports rail-to-rail *differential* input voltage range-meaning the difference between +IN and –IN can reach the full supply rail span-but its common-mode input range is (V–) – 0.2 V to (V+) – 2 V. This allows MUX-friendly operation without phase reversal, though it does not accept inputs beyond the rails.
Can TLV9352IDDFR be used as a comparator?
Yes, TLV9352IDDFR is explicitly designed for open-loop comparator use due to its MUX-friendly inputs, no phase reversal behavior, and fast overload recovery (<600 ns). However, it lacks internal hysteresis-external positive feedback is required for clean switching in noisy environments.
What is the thermal resistance (RθJA) of TLV9352IDDFR in its SOT-23-8 package?
The junction-to-ambient thermal resistance (RθJA) for TLV9352IDDFR in the DDF (SOT-23-8) package is 143.5°C/W under standard JEDEC PCB conditions. This value assumes a 2-layer board with 1-in² copper pour; adding thermal vias reduces effective RθJA by ~20% in production layouts.
Is TLV9352IDDFR qualified for automotive applications?
TLV9352IDDFR is specified for –40°C to 125°C operation and meets industrial reliability standards, but it is not AEC-Q200 qualified. For automotive use, TI recommends the pin-compatible TLV9352QPWRQ1-a qualified variant with identical electrical specs and enhanced qualification testing.
