MAX1240ACSA

\+ 2.7V ，低功耗， 12位串行ADC的8引脚SO +2.7V, Low-Power, 12-Bit Serial ADCs in 8-Pin SO

General Description

The MAX1240/MAX1241 low-power, 12-bit analog-to digital converters ADCs are available in 8-pin packages. The MAX1240 operates with a single +2.7V to +3.6V supply, and the MAX1241 operates with a single +2.7V to +5.25V supply. Both devices feature a 7.5µs successive-approximation ADC, a fast track/hold 1.5µs, an on-chip clock, and a high-speed, 3-wire serial interface.
