Analog Devices MAX165 Product Info

The MAX165/MAX166 are high-speed (5μs) microprocessor (μP)- compatible, 8-bit AOCs 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 MXA7575, 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.
