Key Features
- High Dynamic Range: The LTC1419 offers outstanding AC performance with 81.5dB S/(N + D) and 93dB THD at a 100kHz input, and 80dB S/(N + D) and 86dB THD at the Nyquist input frequency of 400kHz.
- Differential Input Sample-and-Hold: Capable of acquiring single-ended or differential input signals up to 20MHz bandwidth with 60dB common mode rejection.
- Low Power Consumption: Draws only 150mW from ±5V supplies and features two digitally selectable power shutdown modes for low power systems.
- µP Compatible Output: 14-bit parallel output port with no pipeline delay, and a separate convert start input and data ready signal (BUSY) for easy connections to FIFOs, DSPs, and microprocessors.
