Product Details

The LTC1414 is a 14-bit, 2.2Msps, sampling A/D converter which draws only 175mW from ±5V supplies. This high performance ADC includes a high dynamic range sample-and-hold, a precision reference and requires no external components.

The LTC1414's high performance sample-and-hold has a full-scale input range of ±2.5V. Outstanding AC performance includes 80dB S/(N + D) and 95dB SFDR with a 100kHz input. The performance remains high at the Nyquist input frequency of 1.1MHz with 78dB S/(N + D) and 84dB SFDR.

The unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 40MHz bandwidth. The 70dB common mode rejection can eliminate ground loops and common mode noise by measuring signal differentially from the source.

The ADC has a microprocessor compatible, 14-bit parallel output port. There is no pipeline delay in the conversion results.
