12-Bit, 5Msps,
Sampling ADC
J anuary 2000
The LTC
1405 is a 5Msps, 12-bit sampling A/D converter
that draws only 115mW from either single 5V or dual
±
5V
supplies. This easy-to-use device includes a high dynamic
range sample-and-hold, a precision reference and a PGA
input circuit.
The LTC1405 has a flexible input circuit that allows full-
scale input ranges of
±
2.048V,
±
1.024V and
±
0.512V. The
input common mode range is rail-to-rail and a common
mode bias voltage is provided for single supply applica-
tions. The input PGA has a digitally selectable 1x or 2x
gain.
Maximum DC specs include
±
1LSB INL and
±
1LSB DNL
over temperature. Outstanding AC performance includes
71.3dB S/(N + D) and 85dB SFDR at the Nyquist input
frequency of 2.5MHz.
The unique differential input sample-and-hold can acquire
single-ended or differential input signals up to its 100MHz
bandwidth. The 75dB common mode rejection allows
users to eliminate ground loops and common mode noise
by measuring signals differentially from the source. A
separate output logic supply allows direct connection to
3V components.
