Precision rail-to-rail op amps for portable medical electronics

Maxim has rolled out the MAX9617/MAX9618, a zero-drift, rail-to-rail operational amplifiers targeting portable/handheld medical electronics applications where precision, low-noise performance is important.

Operating from a supply voltage of 1.8V to 5.5V MAX9617/MAX9618 are also suggested for industrial applications where low power and precision matters.

The key highlights:

Achieves both a 10µV (max) input-offset voltage and an input-voltage noise of 1µVP-P from 0.1Hz to 10Hz.
Designed to have minimal 1/f noise
Feature low (5nV/°C, typ) input-offset-voltage drift
Consume 59µA of quiescent current per amplifie
1.5MHz GBW
Low 10pA input bias current
Operating temperature range: -40°C to +125°C

Package:
MAX9617: Tiny 6-pin SC70 package
MAX9618: 8-pin SC70 package

Price: Start at $0.65 for 1k pieces
Availability: Now

Maxim claims, competing "zero drift" operational amplifiers with bandwidth greater than or equal to 1MHz typically consume 10x more quiescent current. The industry-leading speed-to-power ratio of the MAX9617/MAX9618 allows use in a wide range of applications without compromising customer power budgets.
