3 Description

The OPA607 and OPA2607 devices are

decompensated, minimum gain of 6 V/V stable,

general-purpose CMOS operational amplifier with low

noise of 3.8 nV/√ Hz and a GBW of 50 MHz.

The low noise and wide bandwidth of the OPAx607

devices make them attractive for general-purpose

applications which require a good balance between

cost and performance. The high-impedance CMOS

inputs make the OPAx607 devices an ideal amplifier

to interface with sensors with high output impedance

(for example, piezoelectric transducers).

The OPAx607 devices feature a Power Down mode

with a maximum quiescent current of less than 1 μA,

making the device suitable for use in portable batterypowered

applications. The rail-to-rail output (RRO) of

the OPAx607 devices can swing up to 8 mV from the

supply rails, maximizing dynamic range.

The OPAx607 is optimized for low supply voltage

operation as low as 2.2 V (±1.1 V) and up to 5.5 V

(±2.75 V), and is specified over the temperature range

of –40°C to +125°C.
