General Description
The MAX187/MAX189 serial 12-bit analog-to-digital converters (ADCs) operate from a single +5V supply and accept a 0 to 5V analog input. Both parts feature an 8.5Fs successive-approximation ADC, a fast track/hold (1.5Fs), an on-chip clock, and a high-speed 3-wire serial interface.

FEATUREs
♦ 12-Bit Resolution
♦ ±½ LSB Integral Nonlinearity (MAX187A/MAX189A)
♦ Internal Track/Hold, 75kHz Sampling Rate
♦ Single +5V Operation
♦ Low Power: 2µA Shutdown Current 1.5mA Operating Current
♦ Internal 4.096V Buffered Reference (MAX187)
♦ 3-Wire Serial Interface, Compatible with SPI, QSPI, and MICROWIRE
♦ Small-Footprint 8-Pin PDIP and 16-Pin SO
