Control linesPlastic Chip Carrier DS1, DS2, and A/B determine which DAC will accept data.61/4 LSB Endpoint Linearity Data loading is similar to that of a RAMs write cycle. Data canGuaranteed Monotonic be read back onto the same data bus with control line R/W. TheDACs Matched to Within 1% DAC8408 is bus compatible with most 8-bit microprocessors,Microprocessor Compatible including the 6800, 8080, 8085, and Z80. The DAC8408 oper-Read/Write Capability (with Memory) ates on a single +5 volt supply and dissipates less than 20 mW.TTL/CMOS Compatible The DAC8408 is manufactured using PMI’s highly stable,Four-Quadrant Multiplication thin-film resistors on an advanced oxide-isolated, silicon-gate,Single-Supply Operation (+5 V) CMOS process. PMI’s improved latch-up resistant design elimi-Low Power Consumption nates the need for external protective Schottky diodes.Latch-Up Resistant1Available In Die Form ORDERING INFORMATION |
