These operates “stand alone” converters are designed to allow operation with the NSC800 and INS8080A derivative control bus with • Differential analog voltage inputs TRI-STATE output latches directly driving the data • Logic inputs and outputs meet both MOS and bus. These A/Ds appear like memory locations or I/O TTL voltage level specifications ports to the microprocessor and no interfacing logic is • Works with 2.5V (LM336) voltage reference needed. • On-chip clock generator Differential analog voltage inputs allow increasing the • 0V to 5V analog input voltage range with common-mode rejection and offsetting the analog single 5V supply zero input voltage value. In addition, the voltage reference input can be adjusted to allow encoding • No zero adjust required any smaller analog voltage span to the full 8 bits of • 0.3" standard width 20-pin DIP package resolution. • 20-pin molded chip carrier or small outline package CONNECTION DIAGRAM • Operates ratiometrically or with 5 VDC, 2.5 VDC, or analog span adjusted voltage reference ADC080X Dual-In-Line and Small Outline (SO) Packages See Ordering Information KEY SPECIFICATIONS • Resolution: 8 Bits • Total error: ±1/4 LSB, ±1/2 LSB and ±1 LSB • Conversion Time: 100 µs Table 1.
