AD7237JN

The AD7237JN belongs to AD7237 is fabricated in Linear Compatible CMOS (LC2MOS), an advanced, mixed technology process that com- bines precision bipolr circuits with low power CMOS logic, Both paris are available in a 24-pin, 0.3" wide plastic and hers metic dualein-line package (DIP) and are also packaged in a 24- lead small outline (SOIC) package. DACHJRT is a trademark of Analog Devices, Inc. And it is a complete, dual, 12-bit, voltage Output digital-to-analog converter with output amplifiers and Zener voltage reference on a monolithic CMOS chip. No external user trims are required to achieve full specified performance. Both parts are microprocessor compatible, with high speed data latches and interlace logic. The AD7237 has a double buffered interface structure and an 8-bit wide data bus with data loaded to the respective input latch in two write operations. An asynchronous LDAC signal on the AD7237 updates the DAC latches and analog outputs. A REF OUTIREF IN function is provided which allows either she onchip 5 reference or an external reference so be usedas a reference voltage for the part. For single supply operation, two output ranges of 0 to +5V and 9 to +10V are available, while these two ranges plus an additional ii range are available with dual supplies. the output amplifiers are capable of devel- oping +10 across a 2 k, load to gnd.

the features of AD7237JN can be summarized as (1)complete dust 12-bit dac comprising; (2)two 12rbit cmos dacs; (3)on-chip voltage reference; (4)output amplifiers; (5)reference buffer amplifiers; (6)parallel loading structure: ad7247; (7)loading structure: ad7237; (8)single or dual supply operation; (9)law power - 165 mwp typ in single supply.
