LTC1855 - 具停机功能的8通道、±10V 输入 14位、100ksps ADC 转换器
An onboard precision reference minimize external components. The low 40mW power dissipation is made even more attractive with two user selectable power shutdown modes. DC specifications include, ±1.5LSB INL for the LTC1855 and ±1LSB for the LTC1854.
The internal clock is trimmed for 5µs maximum conversion time and the sampling rate is guaranteed at 100ksps. A separate convert start input and data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors.
