The LTC1416 is a 2.2µs, 400ksps, 14-bit sampling A/D converter that draws only 70mW from ±5V supplies. This easy-to-use device includes a high dynamic range sample-and-hold and a precision reference. Two digitally selectable power shutdown modes provide flexibility for low power systems.

The LTC1416’s full-scale input range is ±2.5V. Maximum DC specifications include ±2LSB INL, ±1.5LSB DNL over temperature. Outstanding AC performance includes 80.5dB S/(N + D) and 93dB THD with a 100kHz input, and 80dB S/(N + D) and 90dB THD at the Nyquist input frequency of 200kHz.

The unique differential input sample-and-hold can acquire single-ended or differential input signals up to its 15MHz bandwidth. The 60dB common mode rejection allows users to eliminate ground loops and common mode noise by measuring signals differentially from the source.

The ADC has a µP compatible, 14-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.
