TLV9352IDR Overview
An operational amplifier (op amp) is a high-gain DC-coupled electronic voltage amplifier with differential inputs and a single-ended output. Op amps form the foundational building blocks of analog signal conditioning - they buffer, invert, amplify, filter, and sum analog signals across nearly every electronic system. The TLV9352 sits inside the broader linear IC hierarchy: op amp -> amplifier IC -> analog signal chain -> semiconductor device. Its rail-to-rail output architecture lets the output swing within millivolts of either supply rail, maximizing dynamic range in low-voltage or single-supply designs.
Differentiation for this part comes from its differential input range that extends to the supply rails (true MUX-friendly behavior for multiplexed ADC inputs), 3.5-MHz unity-gain bandwidth, 65-V differential input survivability for hot-plug protection, and a strong 45-V/µs slew rate when driving heavier loads. Low offset drift of ±1.5 µV/°C keeps DC accuracy stable over -40 °C to +125 °C operation. The wide 4.5 V to 40 V supply range (or ±2.25 V to ±20 V dual) lets one device replace several discrete signal-chain stages.
Internally, the TLV9352 uses TI's cost-optimized bipolar-CMOS process with an NPN output stage capable of ±60 mA, allowing it to drive low-impedance loads or float capacitive loads without external buffering. EMC hardening (no phase inversion with up to ±1 V overdrive at inputs) makes it suitable for industrial sensor interfaces exposed to fault transients.
Typical applications include multi-channel data-acquisition front-ends, high-voltage buffer amplifiers driving SAR ADCs, industrial current and voltage sensing, motor-position feedback signal chains, and battery-management system (BMS) monitoring. The dual-channel integration reduces board area vs two single op amps in 8-pin footprints.
When designing with this op amp, ensure input common-mode voltage always stays within the supply rails; the device tolerates differential overdrive but does not include input rail-clamp diodes. Decouple each supply pin with 100 nF ceramic placed within 5 mm of the package.

Typical Applications
TLV9352IDR is suitable for 6 applications: Multi-Channel Data Acquisition Front-End, Industrial Current and Voltage Sensing, Motor Position Feedback Amplifier, Battery Management System (BMS) Monitoring, High-Voltage Active Filter for Signal Conditioning, Audio Line Driver and Headphone Buffer.
Multi-Channel Data Acquisition Front-End
The TLV9352IDR's dual-channel integration in 8-pin SOIC and 40-V supply tolerance make it ideal for multi-channel data-acquisition signal-conditioning boards. Per the TI TLV935x datasheet, each channel delivers 3.5-MHz gain-bandwidth with +/-60 mA output drive, enabling direct drive of 16-bit SAR ADCs without a buffer stage. The MUX-friendly rail-to-rail input accepts rail-exceeding common-mode voltages common in multiplexed sensor arrays, while the +/-350 uV offset keeps DC error below 1 LSB at 16 bits (76 uV/LSB). Designers place one TLV9352 per two ADC channels, reducing BOM count vs two single-channel op amps; this is especially valuable when 8 or more channels must fit on a single industrial backplane. The wide 4.5 V to 40 V supply also lets the part run directly from a 24-V industrial bus.
Recommended
Industrial Current and Voltage Sensing
In industrial current-shunt monitors and voltage-sensing front-ends, the TLV9352IDR delivers the wide 40-V common-mode range needed for high-side and low-side current sensing across a 24-V or 36-V bus. Per TI, the op amp's +/-350 uV offset and +/-1.5 uV/°C drift keep measurement error below 0.05% over -40 °C to +125 °C. With 3.5-MHz bandwidth and 45-V/us slew rate, the part tracks fast transient loads such as solenoid or motor drive currents without slew-rate limiting. The dual-channel SOIC-8 footprint is drop-in compatible with the industry-standard dual op-amp pinout, simplifying PCB layout reuse when migrating from legacy parts like the LM358 (which has lower 32-V supply tolerance).
Recommended
Motor Position Feedback Amplifier
The TLV9352IDR's differential-input rail-to-rail feature makes it well-suited for amplifying resolver or encoder feedback signals in motor-position control loops. Per the TI datasheet, the input stage tolerates differential input voltages up to the supply rails, allowing direct connection to bridge outputs at +/-V levels without external protection clamps. The 3.5-MHz closed-loop bandwidth (at low gain) supports the 10-50 kHz modulation frequencies typical of resolver-to-digital converters; the +/-60 mA output current can drive 1-nF loads directly, eliminating the need for a separate buffer between resolver and RDC chip. Industrial servo designers value the -40 °C to +125 °C operation and the SOIC-8's compatibility with automated assembly lines.
Recommended
Battery Management System (BMS) Monitoring
In multi-cell battery-pack monitoring boards, the TLV9352IDR acts as a precision buffer for individual cell voltages before they are multiplexed into a SAR ADC. Per TI, the op amp's wide supply range (4.5 V to 40 V) matches the 12 V to 36 V battery stacks found in e-bike, e-scooter, and 48V telecom backup applications. The rail-to-rail output maximizes ADC input swing and dynamic range for accurate state-of-charge estimation. The device's low input bias current (1 pA typical) prevents it from draining the cell-voltage divider between ADC sampling cycles, preserving measurement accuracy. Designers often place two TLV9352s (one per IC, four channels total) between the BMS analog front-end and the monitoring microcontroller.
Recommended
High-Voltage Active Filter for Signal Conditioning
Engineers building active filters in industrial signal chains can use the TLV9352IDR as a precision op amp implementing Sallen-Key or multiple-feedback (MFB) low-pass, high-pass, and band-pass topologies. Per the TI TLV935x datasheet, the 3.5-MHz GBW lets designers realize filter corner frequencies up to ~50 kHz with low-noise 45-V/us slew-rate behavior. The 40-V supply capability supports +/-15 V dual-supply filter designs without additional supply-rail generation, while the RRO output maximizes input voltage range for the downstream ADC. The dual-channel integration allows cascaded filter stages (channel A then channel B) within one SOIC-8 footprint, halving board area for two-stage filter designs.
Recommended
Audio Line Driver and Headphone Buffer
While the TLV9352IDR is not optimized for ultra-low-noise audio, its +/-60 mA output current and 45-V/us slew rate make it usable as a robust line driver for industrial audio outputs, public-address (PA) systems, or headphone buffers in test equipment. Per the TI datasheet, the 40-V rail tolerance supports +/-18 V professional audio supplies with 3 dB of headroom, while RRO output maximizes usable audio amplitude in lower-voltage 12-V automotive systems. The dual channel in SOIC-8 lets designers implement stereo buffering without a separate stereo op-amp IC, and the +/-350 uV offset keeps DC bias at the headphone terminal low enough to avoid speaker-pop on power-up.

Design Notes
Decouple each supply pin (V+ pin 8, V-/GND pin 4) with a low-ESR 100 nF X7R ceramic capacitor placed within 5 mm of the package and a bulk 1 uF to 10 uF electrolytic or ceramic capacitor nearby. The TLV9352IDR can deliver up to +/-60 mA continuously - during heavy transient loads, the bulk capacitor prevents supply rail collapse. Estimated: at full 60 mA load and 40 V supply, switching events draw instantaneous current spikes that only a properly-sized bulk capacitor can supply. Per TI's TLV935x datasheet, supply decoupling is critical for preventing instability in RRO op amps.
Route high-impedance input traces (INA-, INA+, INB-, INB+) away from noisy output traces to avoid feedback oscillation. Use a guard ring tied to a low-impedance reference around the op-amp inputs when the source impedance exceeds 10 kohm; the TLV9352IDR's 1-pA typical input bias current makes guarding essential for sub-nA measurement circuits. Place both channels' input and feedback components symmetrically around pins 2-3 and 5-6. The exposed thermal pad is not present on SOIC-8 so no thermal pad stitching is required.
Do not apply input voltages that exceed either supply rail by more than 0.5 V, even though the TLV9352IDR has MUX-friendly rail-tolerant inputs. Per the TI datasheet, exceeding the absolute maximum differential input voltage of +/-5 V can permanently damage the input stage. For harsh industrial environments with potential transients beyond +/-5 V, add external series resistors (>=10 kohm) and clamp diodes (to supply rails). Also ensure the input common-mode voltage stays within the supply range; while the device tolerates rail input, operation outside the rails is not guaranteed.
When driving capacitive loads (>100 pF) at unity gain, add a series isolation resistor of 10 ohm to 100 ohm at the op-amp output to maintain phase margin. The TLV9352IDR's +/-60 mA output stage can drive 1 nF directly, but for capacitive loads beyond this, a snubber network (R-C in parallel from output to inverting input) is recommended to prevent ringing. For SAR ADC driver applications, minimize trace inductance between op-amp output and ADC input by placing the components within 10 mm of each other. Estimated: with 50 pF ADC input capacitance and 6-inch trace, ringing at 10 MHz can degrade SNR by 2-3 dB without proper isolation.
