The LTC
1416 is a 2.2
μ
s, 400ksps, 14-bit sampling A/D
converter that draws only 70mW from
±
5V supplies. This
easy-to-use device includes a high dynamic range sample-
and-hold and a precision reference. Two digitally select-
able power shutdown modes provide flexibility for low
power systems.
The LTC1416’s full-scale input range is
±
2.5V. Maximum
DC specifications include
±
2LSB INL,
±
1.5LSB DNL over
temperature. Outstanding AC performance includes 80.5dB
S/(N + D) and 93dB THD with a 100kHz input, and 80dB
S/(N + D) and 90dB THD at the Nyquist input frequency of
200kHz.
The unique differential input sample-and-hold can ac-
quire single-ended or differential input signals up to its
15MHz 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
μ
P compatible, 14-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 micropro-
cessors.
