Product Details

The LTC1406 is a 20Msps, 8-bit, sampling A/D converter which draws only 150mW from a single 5V supply. This easy-to-use device includes a high dynamic range sample-and-hold with a 250MHz bandwidth.

The LTC1406’s full-scale input range is ±1V. The inputs can be driven differentially or one input can be tied to a fixed voltage and the other input driven with a ±1V bipolar input. Maximum DC specifications include ±1LSB DNL and INL over temperature. Outstanding AC performance includes 48.5dB S/(N + D) and 62dB THD with a 1MHz input; 47.5dB S/(N + D) and 59dB THD at the Nyquist input frequency of 10MHz.

The unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 250MHz 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 an 8-bit parallel output port with separate power supply and ground allowing easy interface to 3V digital systems. The pipelined architecture has five clock cycles of data latency.
