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 wide gain bandwidth 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 battery-

powered 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.
