The ADC804SH is a 12-bit successive approximation analog-to-digital,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.
Inter scaling resistors ADC804SH are provided for the selection of ±2.5V,±5V,±10V,0 to +5V,or 0 to
+10V.Gain and offset errors may be externally trimmed to zero,enabling initial end-point accuracies of better than ±0.012% (±1/2LSB).The ADC804SH has two grades,one completely specified for -25 to +85 operation (ADC804BH),and the other for -55 to +125 operation.
The maximum conversion time of 17sec makes the ADC804SH ideal for a wide range 12-bit applications requiring system throughput sampling rates up to 59kHz.In addition,an external clock may be used to synchronize the converter to the systerm clock or to obtain faster operation.As an added benifit for ADC80 users employing the serial output capability,the ADC804SH is designed to replace or provide an alternate source to ADC80 with a mimimum of circuit board changes and it provides a 40% reduction in conversion time.
