Maxim Integrated MAX165AEWN

Description
The MAX165/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 MAX165/MAX166 operate with a 5V supply and an internal or external 1.23V reference, and accept single-ended (MAX165) or differential (MAX166) voltages ranging from 0V to 2VREF.
The MAX165/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 MAX165/MAX166 can be directly tied to a µP 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 MAX166 is recommended.
