M62381FP Datasheet | Mitsubishi Electric

MITSUBISHI<Dig.Ana.INTERFACE> 8-BIT 8CH MULTIPLYING D-A CONVERTER WITH BUFFER AMPLIFIERS DESCRIPTION The M62381FP is an integrated circuit semiconductor of CMOS structure with 8 channels of built-in 8-bit resolution multiplication type D-A converters. The input data is a easy-to-use 3-wire serial transfer method and it is able to cascading serial use with Do terminal. This device is capable of 4 quadrant multiplication because of built-in inverting type amplifier.
