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.
