5 MHz zero-drift amp with 0.4 µV offset — the precision signal-chain anchor
The LMP2022MA/NOPB is a dual-channel zero-drift operational amplifier that delivers 5 MHz gain-bandwidth product and a 0.4 µV typical input offset voltage — a combination that lets it serve as the front-end amplifier in precision DC measurement, load-cell conditioning, thermocouple amplification, or any low-frequency signal path where offset drift and 1/f noise would otherwise corrupt the measurement. Drawing 1.1 mA per channel from a 2.2 V to 5.5 V supply, the part fits into battery-powered or single-rail designs without a negative rail. The 25 pA input bias current means the amplifier does not load high-impedance sensors or precision resistor dividers.
Zero-drift architecture — what 0.4 µV offset buys you in a real circuit
The zero-drift topology continuously auto-corrects the input offset voltage, keeping it at 0.4 µV typical across temperature and time. A standard precision op-amp with 100 µV offset drifts by several microvolts per degree — in a gain-of-1000 stage that drift appears as millivolts at the output and looks like a false signal. The LMP2022's drift is negligible by comparison, so the output error stays within the ADC's LSB over the -40°C to 125°C range. Slew rate of 2.6 V/µs is ample for the DC-to-low-kHz signals that zero-drift amplifiers typically handle. The 50 mA output drive lets the amplifier swing into the input of a successive-approximation ADC's sampling capacitor without an external buffer.
Active production — sourced per RFQ
Texas Instruments lists the LMP2022MA/NOPB as an active product — no end-of-life notice, no last-time-buy window. Routinely sourced through authorized and independent distribution channels. Current pricing and lead time confirmed at quote time against your BOM quantity. ROHS3 compliant. Declaration of conformity and material composition data available on request.
8-SOIC package — standard 0.154-inch footprint
Housed in an 8-pin SOIC (0.154-inch body width, 3.90 mm), the part shares the same PCB footprint as hundreds of industry-standard op-amps. A layout already designed for a general-purpose 8-SOIC op-amp accepts the LMP2022 with no board change.
