Typical Applications
LMP8350MA/NOPB is suitable for 6 applications: High-Speed Precision Data Acquisition, Industrial Process Control and PLC Analog Input, Medical Imaging and Ultrasound Front End, Communications Receiver and SDR, Test and Measurement Instrumentation, Portable and Battery-Powered Instrumentation.
High-Speed Precision Data Acquisition
The LMP8350MA/NOPB fits high-speed precision data acquisition front ends because its fully-differential output directly matches the differential input structure of modern ADC converters, suppressing common-mode noise and even-order distortion. In a typical DAQ channel, the driver converts a single-ended sensor signal into a balanced signal before the ADC. The MODE pin allows the board to switch between low-power and high-performance operation as acquisition rate changes. The SOIC-8 package keeps the signal path compact. For best results, pair it with a precision reference and low-jitter sampling clock.
Recommended
Industrial Process Control and PLC Analog Input
In industrial process control and PLC analog input modules, the LMP8350MA/NOPB drives the measurement ADC after input scaling, filtering, and protection. Its ultra-low-distortion performance prevents the driver from limiting 16-bit accuracy, and the -40C to +85C operating range supports industrial enclosures. The selectable power modes let the module reduce dissipation in idle conditions while retaining high AC performance during active conversions. Use it with a precision SAR ADC and careful grounding to achieve stable readings across temperature.
Recommended
Medical Imaging and Ultrasound Front End
Medical imaging and ultrasound systems need exceptional dynamic range and low spurious response to resolve small echoes. The LMP8350MA/NOPB's fully-differential architecture rejects common-mode interference in the transducer front end, while high power mode maximizes AC performance for low-amplitude signals. The compact SOIC-8 package enables dense multi-channel arrays. Pairing the driver with a high-speed, high-resolution ADC preserves image quality and measurement consistency in diagnostic instruments.
Recommended
Communications Receiver and SDR
Software-defined radio and communications receivers use the LMP8350MA/NOPB to drive wideband ADCs without adding distortion that would degrade spurious-free dynamic range. The differential output matches modern ADC inputs, and the selectable power modes let the receiver reduce current consumption in lower-performance modes or maximum performance when the channel needs full dynamic range. It is well suited for IF sampling and direct RF-sampling data converters in compact radio front ends.
Recommended
Test and Measurement Instrumentation
Automated test equipment and benchtop instrumentation require repeatable, low-distortion signal paths. The LMP8350MA/NOPB is a precision ADC driver that preserves converter accuracy while allowing the instrument to optimize power dissipation through its mode pin. The fully-differential topology reduces even-order harmonics that can bias measured results. Use this driver with a high-accuracy SAR or delta-sigma ADC and a low-noise reference to maintain measurement fidelity in production test systems.
Recommended
Portable and Battery-Powered Instrumentation
Portable and battery-powered instrumentation benefits from the LMP8350MA/NOPB's three selectable power modes, which allow the circuit to drop to a lower current mode between measurements. The fully-differential architecture maintains accuracy for sensor acquisition while the small SOIC-8 package minimizes board space. For intermittent sensor readings, the driver can be biased in low-power mode and switched to high-AC-performance mode only during conversion. This flexibility is valuable in handheld devices where battery life matters.

Key Differentiators
- Three selectable power modes optimize power versus AC performance (vs THS4131CD)
- Ultra-low-distortion fully-differential precision ADC driver in SOIC-8 (vs AD8138ARDZ)
- Lead-free RoHS-compliant /NOPB finish with tube packaging (vs AD8139ARDZ)
Design Notes
Route the differential input and output pairs symmetrically on the PCB to preserve balance and minimize common-mode pickup. Place 0.1 uF supply decoupling capacitors as close as possible to the V+ and V- pins, and use a solid ground plane beneath the device. Keep feedback and gain-setting resistors close to the pins and match trace lengths for the differential paths to avoid skew that can degrade distortion performance.
Use the MODE pin to select one of the three power modes according to system requirements. In high power mode, supply current is higher but AC performance is maximized; in lower modes, distortion and bandwidth may trade off for reduced consumption. Provide adequate supply bypass and verify that the selected mode still meets the ADC's required SNR and SFDR. For battery-powered systems, consider switching to low-power mode during inactive periods.
Do not exceed the absolute maximum ratings in the TI LMP8350 datasheet. Verify the output common-mode voltage required by the connected ADC and adjust the driver's common-mode control accordingly. Because the verified web data snapshot did not include a pin-by-pin pinout table, consult the official datasheet pin configuration before final layout or before substituting any alternative device.
