General Description
The MAX1134/MAX1135 are 150ksps, 16-bit ADCs. These serially interfaced ADCs connect directly to SPI™, QSPI™, and MICROWIRE™ devices without external logic. They combine an input scaling network, internal track/hold (T/H), clock, and three general-purpose digital output pins (for external multiplexer or PGA control) in a 20-pin SSOP package. The excellent dynamic performance (THD ≥ 90dB), high speed (150ksps in bipolar mode), and low power (8.0mA) of these ADCs make them ideal for applications such as industrial process control, instrumentation, and medical applications.
