LINEAR TECHNOLOGY LTC1282 Manual
Update: 30 September, 2023
The LTC1282 is a 12-bit A/D converter with a sampling rate of 140ksps and is powered by a single supply with a power consumption of 12mW. It has a built-in 1.14µs sample and hold, a high-precision reference voltage and an internal calibrated clock. It supports single-ended and bipolar conversion modes. The device is built with LTBiCMOS TM switched capacitor technology. It has a 25ppm/°C (max) internal reference voltage, which converts 0V to 2.5V single-ended inputs from a single 3V supply. With ±3V supplies, the input range is ±1.25V with two's complement output format. The maximum DC specifications include ±0.5LSB INL, ±0.75LSB DNL, and 25ppm/°C full-scale drift over temperature. Outstanding AC performance includes 69dB S/(N + D) and 77dB THD at the Nyquist input frequency of 70kHz. The internal clock is trimmed for a maximum conversion time of 6µs. The clock automatically synchronizes to each sample command, eliminating problems with asynchronous clock noise found in competitive devices. A high-speed parallel interface simplifies connections to FIFOs, DSPs, and microprocessors.
