MAX194BCWE+

MAXIM INTEGRATED PRODUCTS  MAX194BCWE+  模数转换器, 10uA关断, 14 bit, 85 kSPS, 双 +/-, 4.75 V, 5.25 V, WSOIC

The is a 14bit, 85Ksps ADC with 10µA shutdown in 16 pin WSOIC package. It is a 14bit SAR ADC that combines high speed, high accuracy, low power consumption and a 10µA shutdown mode. Internal calibration circuitry corrects linearity and offset errors to maintain the full rated performance over the operating temperature range without external adjustments. The capacitive-DAC architecture provides an inherent 85Ksps track/hold function. The MAX194 with an external reference up to +5V, offers a unipolar 0V to VREF or bipolar -VREF to VREF pin-selectable input range. Separate analogue and digital supplies minimize digital-noise coupling. The chip select input controls the three-state serial- data output. The output can be read either during conversion as the bits are determined or following conversion at up to 5Mbps using serial clock. The EOC output can be used to interrupt a processor or can be connected directly to convert input for continuous, full-speed conversions.
