19-1156; Rev 2; 6/98 +2.
7V to +5.
25V, Low-Power, 10-Bit Serial ADCs in SO-8 __________________General Description The MAX1242/MAX1243 are low-power, 10-bit analogto-digital converters (ADCs) available in 8-pin packages.
They operate with a single +2.
7V to +5.
25V supply and 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.
Power consumption is only 3mW (VDD = 3V) at the 73ksps maximum sampling speed.
A 2µA shutdown mode reduces power at slower throughput rates.
The MAX1242 has an internal 2.
5V reference, while the MAX1243 requires an external reference.
The MAX1243 accepts signals from 0V to VREF, and the ref...
