LTC1409 Overview
Key Features
- This easy-to-use device includes a high dynamic range sampleand-hold and a precision reference
- Two digitally selectable power Shutdown modes provide flexibility for low power systems
- The LTC1409 full-scale input range is ± 2.5V
- Maximum DC specs include ± 1LSB INL and ± 1LSB DNL over temperature
- Outstanding AC performance includes 72.5dB S/(N + D) at the Nyquist input frequency of 400kHz
- The unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 20MHz bandwidth
- The ADC has a µP compatible, 12-bit parallel output port
- There is no pipeline delay in the conversion results
- A separate convert start input and a data ready signal (BUSY) ease connections to FIFOs, DSPs and microprocessors
- A digital output driver power supply pin allows direct connection to 3V logic
