ADC Single SAR 200ksps 8-bit Parallel 20-Pin SOIC W T/R

The MAX166 are high-speed (5µs) microprocessor (µP)- compatible, 8-bit ADCs with track/hold (T/H). The T/H function allows full-scale signals up to 50kHz (386mV/µs slew rate) to be acquired and digitized accurately. Both ADCs use a successive approximation technique to achieve fast conversions and low power dissipation. The MAX166 operate with a +5V supply and an internal or external +1.23V reference, and accept differential voltages ranging from 0V to 2VREF. The MAX166 are easily interfaced to all popular 8-bit µPs through standard /CS and /RD control signals. These signals control the start of conversions and data access. A /BUSY signal indicates the beginning and end of conversions. Since all the data outputs are latched and three-state buffered, the MAX166 can be directly tied to a IP data bus or system input/output port. The MAX165 is a plug-in replacement for the MX7575, with the addition of an internal 1.23V reference. For applications that require a differential analog input and an internal reference, the MAX is recommended.
