The LTC
®
1273/LTC1275/LTC1276 are 300ksps, sam-
pling 12-bit A/D converters that draw only 75mW from
single 5V or
±5V
supplies. These easy-to-use devices
come complete with 600ns sample-and-holds, precision
references and internally trimmed clocks. Unipolar and
bipolar conversion modes provide flexibility for various
applications. They are built with LTBiCMOS
TM
switched
capacitor technology.
These devices have 25ppm/°C (max) internal references.
The LTC1273 converts 0V to 5V unipolar inputs from a
single 5V supply. The LTC1275/LTC1276 convert
±2.5V
and
±5V
respectively from
±5V
supplies. Maximum DC
specifications include
±1/2LSB
INL,
±3/4LSB
DNL and
25ppm/°C full scale drift over temperature. Outstanding
AC performance includes 70dB S/(N + D) and 77dB THD
at the Nyquist input frequency of 150kHz.
The internal clock is trimmed for 2.7µs maximum conver-
sion time. The clock automatically synchronizes to each
sample command eliminating problems with asynchro-
nous clock noise found in competitive devices. A high
speed parallel interface eases connections to FIFOs, DSPs
and microprocessors.
