The LTC
®
1417 is a low power, 400ksps, 14-bit A/D con-
verter. This versatile device can operate from a single 5V or
±5V
supplies. An onboard high performance sample-and-
hold, a precision reference and internal trimming minimize
external circuitry requirements. The low 20mW power
dissipation is made even more attractive with two user-
selectable power shutdown modes.
The LTC1417 converts 0V to 4.096V unipolar inputs when
using a 5V supply and
±2.048V
bipolar inputs when using
±5V
supplies. DC specs include
±1.25LSB
INL,
±1LSB
DNL and no missing codes over temperature. Outstanding
AC performance includes 81dB S/(N + D) and – 95dB THD
at a Nyquist input frequency of 200kHz.
The internal clock is trimmed for 2µs maximum conver-
sion time. A separate convert start input and a data ready
signal (BUSY) ease connections to FIFOs, DSPs and
microprocessors.
