put amplifiers. No external user trims are required to
achieve full specified performance. The MAX532鈥檚 3-
parts. The interface is SPI鈩? QSPI鈩?and Microwire鈩?/div>
compatible. A serial output, DOUT, allows cascading
of two or more MAX532s and read-back of the data
written to the device.
The device鈥檚 serial interface minimizes digital-noise
feedthrough from its logic pins to its analog outputs.
Serial interfacing also simplifies opto-coupler-isolated
or transformer-isolated applications.
The MAX532 is specified with 鹵12V to 鹵15V power sup-
plies. All logic inputs are TTL and CMOS compatible. It
comes in space-saving 16-pin DIP and wide SO packages.
