Product Details
| DESCRIPTION The 10-bit LTC®1852 and 12-bit LTC1853 are complete 8-channel data acquisition systems. They include a flexible 8-channel multiplexer, a 400ksps successive approximation analog-to-digital converter, an internal reference and a parallel output interface. The multiplexer can be configured for single-ended or differential inputs, two gain ranges and unipolar or bipolar operation. The ADCs have a scan mode that will repeatedly cycle through all 8 multiplexer channels and can also be programmed to sequence through up to 16 addresses and configurations. The sequence can also be read back from internal memory. FEATURES ■ Flexible 8-Channel Multiplexer Single-Ended or Differential Inputs Two Gain Ranges Unipolar or Bipolar Operation ■ Scan Mode and Programmable Sequencer Eliminate Confi guration Software Overhead ■ Low Power: 3mW at 250ksps ■ 2.7V to 5.5V Supply Range ■ Internal or External Reference Operation ■ Parallel Output Includes MUX Address ■ Nap and Sleep Shutdown Modes ■ Pin Compatible up-grade 1.25Msps 10-Bit LTC1850 and 12-Bit LTC1851 APPLICATIONS ■ High Speed Data Acquisition ■ Test and Measurement ■ Imaging Systems ■ Telecommunications ■ Industrial Process Control ■ Spectrum Analysis |
