This easy-to-use device includes a high dynamic range sampleand-hold and a precision reference. Two digitally selectable power Shutdown modes provide flexibility for low power systems. The LTC1409 full-scale input range is ± 2.5V. Maximum DC specs include ± 1LSB INL and ± 1LSB DNL over temperature. Outstanding AC performance includes 72.5dB S/(N + D) at the Nyquist input frequency of 400kHz. The ADC has a µP compatible, 12-bit parallel output port. There is no pipeline delay in the conversion results.
