GENERAL DESCRIPTION
The
are single/dual/quad, rail-to-
rail, input and output, single-supply amplifiers featuring very
low offset voltage, wide signal bandwidth, and low input voltage
and current noise. The parts use a patented trimming technique
that achieves superior precision without laser trimming. The
are fully specified to operate from
2.7 V to 5 V single supplies.
The combination of >20 MHz bandwidth, low offset, low noise,
and low input bias current makes these amplifiers useful in a
wide variety of applications. Filters, integrators, photodiode
amplifiers, and high impedance sensors all benefit from the
combination of performance features. AC applications benefit from
the wide bandwidth and low distortion. The
offer the highest output drive capability of the DigiTrim®
family, which is excellent for audio line drivers and other low
impedance applications.
Applications for the parts include portable and low powered
instrumentation, audio amplification for portable devices,
portable phone headsets, bar code scanners, and multipole
filters. The ability to swing rail-to-rail at both the input and
output enables designers to buffer CMOS ADCs, DACs, ASICs,
and other wide output swing devices in single-supply systems.
