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.
