LTC1864CS8#PBF

LTC®1864 is a 16bit 1 channel µPower A/D converter. The supply current drops at lower speeds because the LTC1864 automatically power down between conversions. This 16bit switched capacitor successive approximation ADCs include sample-and holds. This 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. Application includes high speed data acquisition, portable or compact instrumentation, low power battery-operated instrumentation, isolated and/or remote data acquisition.
