Product Details
| DESCRIPTION The LTC®1854/LTC1855/LTC1856 are 8-channel, low power, 12-/14-/16-bit, 100ksps, analog-to-digital converters (ADCs). These ADCs operate from a single 5V supply and the 8-channel multiplexer can be programmed for single-ended inputs, pairs of differential inputs, or combinations of both. In addition, all channels are fault protected to ±30V. A fault condition on any channel will not affect the conversion result of the selected channel. FEATURES ■ Single 5V Supply ■ Sample Rate: 100ksps ■ 8-Channel Multiplexer with ±30V Protection ■ ±10V Bipolar Input Range Single Ended or Differential ■ ±3LSB INL for the LTC1856, ±1.5LSB INL for the LTC1855, ±1LSB INL for the LTC1854 ■ Power Dissipation: 40mW (Typ) ■ SPI/MICROWIRETM Compatible Serial I/O ■ Power Shutdown: Nap and Sleep ■ SINAD: 87dB (LTC1856) ■ Operates with Internal or External Reference ■ Internal Synchronized Clock ■ 28-Pin SSOP Package APPLICATIONS ■ Industrial Process Control ■ Multiplexed Data Acquisition Systems ■ High Speed Data Acquisition for PCs ■ Digital Signal Processing |
