23• Easy interfacetoall microprocessors DESCRIPTIONThe ADC0816, ADC0817 data acquisition component
• Operates ratiometricallyor with5 VDCora monolithic CMOS device with an 8-bit analog-to-
analog span adjusted voltage reference digital converter,16-channel multiplexer and
• 16-channel multiplexer with latched control microprocessor compatible control logic. The 8-bit
logic A/D converter uses successive approximationas the
Outputs meet TTL voltage level specifications conversion technique. The converter featuresa high
impedance chopper stabilized comparator,a 256R
• 0Vto 5V analog input voltage range with voltage divider with analog switch tree anda
single 5V supply successive approximation register. The 16-channel
• No zeroor full-scale adjust required multiplexer can directly access any oneof 16-single-
Standard hermeticor molded 40-pin MDIP ended analog signals, and provides the logic for
package additional channel expansion. Signal conditioningof
any analog input signalis eased by direct accessto
• Temperature range −40°Cto +85°Cor −55°Cto the multiplexer output, andto the inputof the 8-bit
+125°C A/D converter.
• Latched TRI-STATE output The device eliminates the need for external zero and
• Direct accessto “comparator in” and full-scale adjustments. Easy interfacing to
“multiplexer out” for signal conditioning microprocessors is provided by the latched and
• ADC0816 equivalentto MM74C948 decoded multiplexer address inputs and latched TTL
TRI-STATE® outputs.
• ADC0817 equivalentto MM74C948-1The design of the ADC0816, ADC0817 has been
KEY SPECIFICATIONS optimizedby incorporating the most desirable aspects several A/D conversion techniques. The
• Resolution ........................8 Bits ADC0816,ADC0817 offers high speed, high
• Total Unadjusted Error....±½ LSB and±1 accuracy, minimal temperature dependence,
Single Supply....................5 VDC excellent long-term accuracy and repeatability, and
consumes minima lpower. These features make this
• Low Power........................15 mW device ideally suitedto applications from process and
µs machine control to consumer and automotive
applications. For similar performanceinan 8-channel,
28-pin, 8-bit A/D converter, see the ADC0808,
ADC0809 data sheet. (See AN-258 for more
