The single LMP2231, dual LMP2232, and quad LMP2234 micropower precision operational amplifiers provide guaranteed maximum offset voltage drift over temperature (TCVOS) as low as ±0.4 μV/C. All three op amps have a power consumption of less than 16 μW per channel, while providing 130 kHz of usable bandwidth.
Features include CMOS inputs, 1.6 to 5.5-V operation, 10 μA of supply current per channel, low offset voltage of 150 μV, and a wide temperature range of −40° to 125°C. The LMP2231 is offered in 5-pin SOT23 and 8-pin SOIC packages, the LMP2232 is offered in 8-pin SOIC or 8-pin MSOP packages, and the LMP2234 is offered in 14-pin SOIC or 14-pin TSSOP packages. (From $1.10 to $2.35 ea/1,000—available now.)
