LP2902N/NOPB

Instrumentation, Op Amps, Buffer Amps Overview

The LP2902N/NOPB is a quad low-power operational amplifier manufactured by Texas Instruments. It features four independent amplifiers in a single package, designed for wide voltage operation from 3V to 32V. Key electrical specifications include a gain-bandwidth product of 100 kHz and a slew rate of 50 mV/µs. The device operates with a typical supply current of 85 µA per channel and provides an output current capability of 10 mA. Input characteristics include a maximum input offset voltage of 4 mV and an input bias current of 20 nA. The component supports rail-to-rail input functionality and offers a common-mode rejection ratio of 90 dB. It is housed in a 14-pin PDIP package suitable for through-hole mounting.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'NOPB' indicates lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the package type corresponds to the standard 14-pin PDIP form factor. Ensure the operating temperature range aligns with industrial requirements. Cross-reference the manufacturer part number against official distributor catalogs to validate authenticity and current production status before procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple low-speed amplification channels are required in space-constrained designs. The rail-to-rail input feature makes it suitable for single-supply systems where signals approach ground level. Compare the 100 kHz bandwidth against application signal frequencies to ensure adequate response time. Evaluate the 85 µA supply current against strict power budget constraints typical in portable devices.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the LP2902 family of ultra-low-power quad operational amplifiers. It shares functional similarities with the LM2902 but offers improved power efficiency and rail-to-rail input capabilities. The N suffix denotes the PDIP package variant, while NOPB signifies non-plumbum (lead-free) construction compliant with environmental directives.
