Product details
Overview
TLV9352IDGKR from Texas Instruments is a dual-channel, rail-to-rail output, 3.5-MHz gain-bandwidth 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 noise at 1 kHz, 20 V/µs slew rate, and operates from 4.5 V to 40 V supply. It is used in motor drive power stage modules where robust MUX-friendly inputs and differential input range to the rails enable reliable signal conditioning under dynamic common-mode shifts.
For engineers reviewing the TLV9352IDGKR datasheet, TLV9352IDGKR pinout, TLV9352IDGKR application, or TLV9352IDGKR equivalent, key selection criteria include its 40-V supply capability, ±60 mA output drive, EMI-hardened inputs, rail-to-rail output swing within 10 mV of rails (no-load), and guaranteed operation from –40°C to 125°C in industrial environments.
Technical Context
The TLV9352IDGKR implements a high-slew-rate, low-noise CMOS input stage with EMI/RFI filtering on both inputs, enabling stable operation in noisy industrial settings. Its MUX-friendly architecture supports differential input voltages up to the supply rails and allows open-loop use as a comparator without phase reversal.
It features dual independent amplifiers sharing a single 4.5–40 V supply, with each channel drawing only 600–800 µA quiescent current. The device maintains 110 dB CMRR and 130 dB open-loop gain across temperature, supporting precision closed-loop configurations in servo control feedback paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 3.5 MHz - Enables stable unity-gain buffer or G = 10 amplification up to 350 kHz without peaking. |
| Slew rate | 20 V/µs - Supports fast 10-V step response in ≤500 ns, critical for motor current sensing and PWM reconstruction. |
| Input offset voltage | ±0.35 mV (max) - Ensures <0.1% error in 3.3-V reference-based current shunt amplifiers at room temperature. |
| Supply voltage range | 4.5 V to 40 V - Directly interfaces with 24-V industrial buses and 36-V motor drive rails without external regulators. |
| Output drive current | ±60 mA - Drives 67 Ω loads (e.g., terminated transmission lines) or multiple downstream logic inputs without buffering. |
| EMI rejection ratio | ≥60 dB @ 1 GHz - Mitigates RF ingress from switching power supplies and motor commutation noise. |
| Operating temperature | –40°C to +125°C - Qualified for under-hood automotive and industrial motor control enclosures. |
Pinout & Package
VSSOP-8 (DGK) package: 3.0 mm × 3.0 mm body, 0.65 mm pitch, thermally enhanced exposed pad for improved power dissipation in dual-channel operation.
| 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 rail-to-rail common-mode operation in sensor front-ends. |
| –IN A (Pin 2) | Inverting input, Channel A | Differential input voltage range extends to supply rails; usable in comparator mode with hysteresis networks. |
| OUT A (Pin 1) | Output, Channel A | Rail-to-rail swing: within 10 mV of V+ and V– at no load; sustains ±60 mA short-circuit current. |
| V– (Pin 4) | Negative supply | Reference for both channels; supports single-supply (ground-referenced) or split-supply (±20 V) configurations. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent of Channel A; allows dual-path signal conditioning (e.g., current + voltage sensing in same module). |
| –IN B (Pin 6) | Inverting input, Channel B | EMI-filtered input; immune to RF coupling in proximity to gate drivers or IGBTs. |
| OUT B (Pin 7) | Output, Channel B | Matches OUT A performance; supports parallel output stages or differential output configurations. |
| V+ (Pin 8) | Positive supply | Maximum 40 V absolute rating; internal protection diodes clamp transients beyond (V+) + 0.5 V or (V–) – 0.5 V. |
Key Features
| Feature | Design Value |
|---|---|
| MUX-friendly inputs | Differential input voltage range spans full supply rails (V– to V+), eliminating need for level-shifting when multiplexing multiple sensors. |
| Rail-to-rail output | Delivers full dynamic range: 0.01 V headroom to V+ and V– at no load, preserving resolution in 12-bit ADC interfaces. |
| High EMI rejection | Integrated RFI filters suppress >60 dB of 900-MHz cellular and 2.4-GHz Wi-Fi interference, reducing post-processing filtering. |
| Low quiescent current | 650 µA per amplifier enables always-on monitoring in battery-backed PLC I/O modules without compromising runtime. |
| Robust overload recovery | Recovers from output saturation in ≤600 ns, preventing latch-up during motor stall or short-circuit events. |

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 tighter layout for stability. | Better for metrology-grade measurements; overqualified for motor drive feedback where cost and power dominate. | Choose TLV9352IDGKR for cost-sensitive 40-V industrial systems needing robustness over ultra-low offset. |
| LM358BDR | Wider temp range (–40°C to 125°C), but only 700-kHz GBW, ±2-mV offset, and 36-V max supply; no EMI filtering. | Suitable for basic signal buffering in non-noisy environments; lacks MUX-friendliness and rail-to-rail output. | TLV9352IDGKR provides 5× bandwidth, 6× lower offset, and EMI hardening-critical for modern motor drives. |
Compared with OPA2182IDR and LM358BDR, TLV9352IDGKR uniquely balances 40-V operation, 3.5-MHz bandwidth, ±350 µV offset, and integrated EMI filtering-making it optimal for industrial motor control where cost, noise immunity, and supply flexibility are co-prioritized.

FAQ
What is the maximum supply voltage for TLV9352IDGKR?
The TLV9352IDGKR supports an absolute maximum supply voltage of 42 V between V+ and V–, with recommended operation from 4.5 V to 40 V. This wide range allows direct integration into 24-V and 36-V industrial power rails without regulation, and its internal protection diodes clamp transient excursions beyond (V+) + 0.5 V or (V–) – 0.5 V.
Does TLV9352IDGKR support rail-to-rail input operation?
TLV9352IDGKR supports rail-to-rail *output* swing but not full rail-to-rail *input*. Its common-mode input voltage range extends from (V–) – 0.2 V to (V+) – 2 V. This enables operation with inputs near the negative rail and accommodates most industrial sensor outputs, though inputs within 2 V of V+ require external attenuation or level shifting.
Can TLV9352IDGKR be used as a comparator?
Yes, TLV9352IDGKR can be used open-loop as a comparator due to its MUX-friendly inputs and absence of phase reversal. Its differential input range extends to the supply rails, and it recovers from overload in ≤600 ns. However, it lacks built-in hysteresis or push-pull output-external resistors or post-amplification may be needed for clean digital transitions.
What is the thermal resistance (RθJA) of TLV9352IDGKR in its VSSOP-8 package?
The TLV9352IDGKR in the DGK (VSSOP-8) package has a junction-to-ambient thermal resistance (RθJA) of 177.1°C/W, as specified in the datasheet's Thermal Information section. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves with PCB copper pour and thermal vias beneath the exposed pad.
Is TLV9352IDGKR qualified for automotive applications?
TLV9352IDGKR is not AEC-Q100 qualified. It is rated for industrial operation from –40°C to +125°C and is widely used in automotive-adjacent applications like onboard chargers and battery management subsystems-but for safety-critical ADAS or powertrain functions, TI's automotive-grade alternatives (e.g., TLV9302-Q1) must be selected instead.
