LTC1409 12-Bit, 800ksps SamplingA/D Converter with Shutdown

The LTC™1409 is a 1µs, 800ksps, sampling 12-bit A/D converter that draws only 80mW from ±5V supplies. This easy-to-use device includes a high dynamic range sample-and-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 unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 20MHz bandwidth. The 60dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source. The ADC has a µP compatible, 12-bit parallel output port. There is no pipeline delay in the conversion results. A separate convert start input and a data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors. A digital output driver power supply pin allows direct connection to 3V logic
