OPA345NA/250 Datasheet

Operational Amplifiers - Op Amps


The OPA344 and OPA345NA/250 series rail-to-rail CMOS operational amplifiers are designed for precision, low-power,miniature applications. The OPA344 is unity gain stable,while the OPA345NA/250 is optimized for gains greater than or equal to five, and has a gain-bandwidth product of 3MHz.The OPA344 and OPA345NA/250 are optimized to operate on a single supply from 2.5V and up to 5.5V with an input common-mode voltage range that extends 300mV beyond the supplies. Quiescent current is only 250μA (max). OPA345NA/250 Features • Rail-To-Rail Input• Rail-To-Rail Output (Within 1mv)• Low Quiescent Current: 150μA Typ• Microsize Packages Sot23-5 Msop-8 Tssop-14• Gain-Bandwidth Opa344: 1mhz, G ≥ 1 Opa345: 3mhz, G ≥ 5• Slew Rate Opa344: 0.8v/μS Opa345: 2v/μS• Thd + Noise: 0.006%
