The MAX170 is a complete CMOS 12-bit A/D converter that combines high speed and accurate performance with a cost and space saving serial interface in an 8-load DIP or 16-lead surface mount SO package. It uses a high speed DAC and an accurate comparator in a successive approximation loop to achieve a 5.6μs conversion time. An on-chip buried-zener reference provides low-drift performance over the full temperature range.
External components arc limited only to supply and reference decoupling capacitors The CLOCK input can be driven from an external clock source such as a divided-down microprocessor clock. The MAX170 works with +5V and -12V to -15V supply voltages, typically dissipating 135mW.
The MAX170 is designed to work with general purpose serial-to-parallel converters, such as the 74HC595. It can also be used with digital-signal-processors such as the TMS32020. TMS320C25, NEC μPD7720 or the DSP56000. The MAX170 has a three-wire interface that serially outputs a leading one, followed by 12 data bits (MSB first).
When the MAX170 is used with an external sample-and-hold amplifier, a maximum sampling rate of 125kHz is possible.
