Features Compatible with 8080 µP derivatives-no interfacing logic needed - access time - 135 ns Easy interface to all microprocessors, or operates "stand alone" Differential analog voltage inputs Logic inputs and outputs meet both MOS and TTL voltage level specifications Works with 2.5V (LM336) voltage reference On-chip clock generator 0V to 5V analog input voltage range with single 5V supply No zero adjust required 0.3[Prime] standard width 20-pin DIP package 20-pin molded chip carrier or small outline package Operates ratiometrically or with 5 VDC, 2.5 VDC, or analog span adjusted voltage reference Description The ADC0801, ADC0802, ADC0803, ADC0804 and ADC0805 are CMOS 8-bit successive approximation A/D converters that use a differential potentiometric ladder-similar to the 256R products. These converters are designed to allow operation with the NSC800 and INS8080A derivative control bus with TRI-STATE output latches directly driving the data bus. These A/Ds appear like memory locations or I/O ports to the microprocessor and no interfacing logic is needed. Differential analog voltage inputs allow increasing the common-mode rejection and offsetting the analog zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding any smaller analog voltage span to the full 8 bits of resolution. Key Specification Resolution 8 bits Total error ±¼ LSB, ±½ LSB and ±1 LSB Conversion time 100 µs

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
