LTC1275 - 12-Bit, 300ksps Sampling A/D Converters with Reference
LTC1275 - 12-Bit, 300ksps Sampling A/D Converters with Reference - Linear Technology（凌力尔特）
The LTC1273/LTC1275/LTC1276 are 300ksps, sampling 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 larcon version modes provide flexibility for various cations. 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 conversion time. The clock automatically synchronizes to each sample command eliminating problems with asynchronous clock noise found in competitive devices. A high speed parallel interface eases connections to FIFOs, DSPs and microprocessors.
