DAC8408H

The DAC8408H is designed as one kind of quad 8-bit multiplying CMOS D/A converter with memory that belongs to the DAC8408 family. This device can be used in (1)voltage set points in automatic test equipment; (2)systems requiring data access for self-diagnostics; (3)industrial automation; (4)multichannel microprocessor-controlled systems; (5)digitally controlled op amp offset adjustment; (6)process control; (7)digital attenuators. Also it combines four identical 8-bit CMOS DACs onto a single monolithic chip. Each DAC has its own reference input, feedback resistor, and on-board data latches.

Features of the DAC8408H are:(1)four DACs in a 28 pin, 0.6 inch wide DIP or 28-pin JEDEC plastic chip carrier; (2)+/- 1/4 LSB endpoint linearity; (3)guaran-teed monotonic; (4)DACs matched to within 1%; (5)microprocessor compatible; (6)read/write capability (with memory); (7)TTL/CMOS compatible; (8)four-quadrant multiplication; (9)single-supply operation (+5 V); (10)low power consumption; (11)latch-up resistant; (12)available in die form.

The absolute maximum ratings of the DAC8408H can be summarized as:(1)VDD to IOUT 2A, IOUT 2B, IOUT 2C, IOUT 2D:0 to +7 V;(2)VDD to DGND:0 to +7 V;(3)IOUT 1A, IOUT 1B, IOUT 1C, IOUT 1D to DGND:-0.3 V to VDD+0.3 V;(4)RFBA, RFBB, RFBC, RFBD to IOUT:±25 V;(5)lead temperature (soldering, 10 sec):+ 300°C;(6)storage temperature:-65°C to +150°C;(7)junction temperature:+150°C;(8)operating temperature range commercial grade (GP):0°C to +70°C;(9)operating temperature range industrial grade:-40°C to +85°C;(10)operating temperature range military grade:-55°C to +125°C.
