LTC1417

Low Power 14-Bit, 400ksps

Sampling ADC Converter

with Serial I/O

FEATURES

DESCRIPTIO

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.

■

16-Pin Narrow SSOP Package (SO-8 Footprint)

■

Sample Rate: 400ksps

■

±1.25LSB INL and ±1LSB DNL Max

■

Power Dissipation: 20mW (Typ)

■

Single Supply 5V or ±5V Operation

■

Serial Data Output

■

No Missing Codes Over Temperature

■

Power Shutdown: Nap and Sleep

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

DNLandnomissingcodesovertemperature. Outstanding

AC performance includes 81dB S/(N + D) and 95dB THD

at a Nyquist input frequency of 200kHz.

■

External or Internal Reference

■

Differential High Impedance Analog Input

■

Input Range: 0V to 4.096V or ±2.048V

■

81dB S/(N + D) and –95dB THD at Nyquist

APPLICATIO S

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.
