DESCRIPTION
The LTC
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.
