LTC1411 Overview
Key Features
- The ADC can be powered down with either the Nap or Sleep mode for low power applications
- The LTC1411 converts either differential or single-ended inputs and presents data in 2’s complement format
- Maximum DC specs include ±2LSB INL and 14-bit no missing code over temperature
- Outstanding dynamic performance includes 80dB S/(N + D) and 90dB THD at 100kHz input frequency
- The LTC1411 has four programmable input ranges selected by two digital input pins, PGA0 and PGA1
- This provides input spans of ±1.8V, ±1.27V, ±0.9V and ±0.64V
- An out-of-the-range signal together with the D13 (MSB) will indicate whether a signal is over or under the ADC’s input range
- A simple conversion start input and a data ready signal ease connections to FIFOs, DSPs and microprocessors
