ANALOG DEVICES LTC1860CMS8#PBF Analogue to Digital Converter, 12 bit, 250 kSPS, Differential, 3 Wire, Microwire, Serial, SPI

LTC1860 is a 1-channel, 12-bit A/D converter. The supply current drops at lower speeds because the device automatically power down to a typical supply current of 1nA between conversions. This 12-bit switched capacitor successive approximation ADC include sample-and-holds. This device has a differential analogue input with an adjustable reference pin. This ADC can be used in ratiometric applications or with external references. The high impedance analogue inputs and the ability to operate with reduced spans down to 1V full scale, allow direct connection to signal sources in many applications, eliminating the need for external gain stages. It is widely used in application such as n high speed data acquisition, portable or compact instrumentation, low power battery-operated instrumentation, isolated and/or remote data acquisition etc.
