1 / 18 page ADC0816, ADC0817 www.ti.com SNAS527C – JUNE 1999 – REVISED MARCH 2013 ADC0816/ADC0817 8-Bit μP Compatible A/D Converters with16-Channel Multiplexer Check for Samples: ADC0816, ADC0817 1 FEATURES 23 • Easy interface to all microprocessors DESCRIPTION The ADC0816, ADC0817 data acquisition component • Operates ratiometrically or with 5 VDC or is a 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 approximation as the • Outputs meet TTL voltage level specifications conversion technique. The converter features a high impedance chopper stabilized comparator, a 256R • 0V to 5V analog input voltage range with voltage divider with analog switch tree and a single 5V supply successive approximation register. The 16-channel • No zero or full-scale adjust required multiplexer can directly access any one of 16-single- • Standard hermetic or molded 40-pin MDIP ended analog signals, and provides the logic for package additional channel expansion. Signal conditioning of any analog input signal is eased by direct access to • Temperature range −40°C to +85°Cor −55°C to the multiplexer output, and to the input of the 8-bit +125°C A/D converter. • Latched TRI-STATE output The device eliminates the need for external zero and • Direct access to “comparator in” and full-scale adjustments. Easy interfacing to “multiplexer out” for signal conditioning microprocessors is provided by the latched and • ADC0816 equivalent to MM74C948 decoded multiplexer address inputs and latched TTL TRI-STATE®outputs. • ADC0817 equivalent to MM74C948-1 The design of the ADC0816, ADC0817 has been KEY SPECIFICATIONS optimized by incorporating the most desirable aspects of 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 suited to applications from process and • Conversion Time..............100 µs machine control to consumer and automotive applications. For similar performance in an 8-channel, 28-pin, 8-bit A/D converter, see the ADC0808, ADC0809 data sheet.
