ADC804SHQ

The ADC804SHQ is designed as a 12-bit successive approximation analog-to-digital converter, custom-designed for freedom from latch-up and for optimum AC performance. It is complete with a comparator, a monolithic 12-bit DAC which includes a 6.3V reference laser-trimmed for minimum temperature coefficient and a CMOS logic chip containing the successive approximation register (SAR), clock and all other associated logic functions.

ADC804SHQ has nine features. (1)17us conversion time. (2)Serial output ideal for applications requiring isolation or long-distance data transmission. (3)<500mW power dissipation. (4)24-pin dual wide hermetic package. (5)Fully specified for operation on +/-12V or +/-15V supplies. (6)+/-0.012% integral linearity. (7)12-bit resolution. (8)Temperature range available for -55°C to 125°C operation. (9)No missing codes -25°C to 85°C. Those are all the main features.

Some absolute maximum ratings of ADC804SHQ have been concluded into several points as follow. (1)Its +Vcc to analog common would be from 0V to +16.5V. (2)Its -Vcc to analog common would be from 0V to -16.5V. (3)Its Vdd to digital common would be from 0V to 7V. (4)Its analog common to digital common would be +/-0.5V. (5)Its logic inputs (convert command, clock in) to digital common would be from -0.3V to +0.5V. (6)Its analog inputs (analog in, bipolar offset) to analog common would be +/-16.5V. (7)Its power dissipation would be 1000mW. (8)Its lead temperature soldering would be 300°C 10 seconds. (9)Its thermal resistance would be 60°C/W. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics are concluded as follow. (1)Its input high voltage would be min 2.0V and max 5.5V. (2)Its input low voltage would be min -0.3V and max +0.8V. (3)Its input current high would be max -150uA. (4)Its input current low would be max 500uA. And so on.
