Differential input voltage range equal to the power supply voltage
GENERAL DESCRIPTION
The CBM2904 contains two independent high gain operational amplifiers with internal
frequency compensation. The two op-amps operate over a wide voltage range from a single
power supply. Also use a split power supply. The device has low power supply current drain,
regardless of the power supply voltage. The low power drain also makes the CBM2904 a good
choice for battery operation.
When your project calls for a traditional op-amp function, now you can streamline your
design with a simple single power supply. Use ordinary +5VDC common to practically any digital
system or personal computer application, without requiring an extra 15V power supply just to
have the interface electronics you need.
The CBM2904 is a versatile, rugged workhorse with a thousand-and-one uses, from
amplifying signals from a variety of transducers to dc gain blocks, or any op-amp function. The
attached pages offer some recipes that will have your project cooking in no time.
