LTC1411
1411f
Single Supply
14-Bit 2.5Msps ADC
The LTC
1411 is a 2.5Msps sampling 14-bit A/D con-
verter in a 36-pin SSOP package, which typically dissi-
pates only 195mW from a single 5V supply. This device
comes complete with a high bandwidth sample-and-
hold, a precision reference, programmable input ranges
and an internally trimmed clock. The ADC can be powered
down with either the Nap or Sleep mode for low power
applications.
The LTC1411 converts either differential or single-ended
inputs and presents data in 2’s complement format.
Maximum DC specs include
±
2LSB INL and 14-bit no
missing code over temperature. Outstanding dynamic
performance includes 80dB S/(N + D) and 90dB THD at
100kHz input frequency.
The LTC1411 has four programmable input ranges se-
lected by two digital input pins, PGA0 and PGA1. This
provides input spans of
±
1.8V,
±
1.27V,
±
0.9V and
±
0.64V.
An out-of-the-range signal together with the D13 (MSB)
will indicate whether a signal is over or under the ADC’s
input range. A simple conversion start input and a data
ready signal ease connections to FIFOs, DSPs and micro-
processors.
