MAX11300GTL+

MAXIM INTEGRATED PRODUCTS  MAX11300GTL+  模数转换器, PIXI, 12 bit, 400 kSPS, 单, 4.75 V, 5.25 V, TQFN

The is a PIXI, 20port programmable mixed-signal I/O with 12bit ADC, 12bit DAC, analogue switches and GPIO in 40 pin TQFN package. It offers 20 mixed-signal high voltage, bipolar ports, which are configurable as an ADC analogue input, a DAC analogue output, a general-purpose input, a general-purpose output or an analogue switch terminal. One internal and two external temperature sensors track junction & environmental temperature. Adjacent pairs of ports are configurable as a logic-level translator for open-drain devices or an analogue switch. PIXI ports provide highly flexible hardware configuration for 12bit mixed-signal applications. Each port is individually configurable with up to 4 selectable voltage ranges within -10V to +10V. It allows for the averaging of 2, 4, 8, 16, 32, 64 or 128 ADC samples from each ADC-configured port to improve noise performance. A DAC-configured output port can drive up to 25mA. The GPIO ports can be programmed to user-defined logic level
