CBM8604
Active
Extremely low offset voltage, RRIO, quad channel operational amplifier

The CBM8601, CBM8602, and CBM8604 are single, dual, and quad rail-to-rail, input and output, single-supply amplifiers featuring very low offset voltage and Gain bandwidth productcharacteristics up to 8.5MHz. These amplifiers use a new, patented trimming technique that achieves superior performance without laser trimming. All are fully specified to operate on a 2.7V to 5.5 V single supply.
The combination of low offsets, very low input bias currents, and high speed make these amplifiers useful in a wide variety of applications. Filters, integrators, diode amplifiers, shunt current sensors, and high impedance sensors all benefit from the combination of performance features. Audio and other ac applications benefit from the wide bandwidth and low distortion. Applications for these amplifiers include audio amplification for portable devices, portable phone headsets, bar code scanners, portable instruments, cellular PA controls, 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.
The CBM8601, CBM8602, and CBM8604 are specified over the extended industrial (−40°C to+125°C) temperature range. The CBM8601, single, is available in a tiny, 5-lead SOT-23 package. The CBM8602, dual, is available in 8-lead MSOP and 8-lead, narrow SOIC surface-mount packages. The CBM8604, quad, is available in 14-lead TSSOP, 14-lead SOIC, and 16-lead QSOP packages.
