LTC1606

1606fa

16-Bit, 250ksps,

Single Supply ADC

The LTC

verter that draws only 75mW (typical) from a single 5V

supply. This easy-to-use device includes sample-and-

hold, precision reference, switched capacitor successive

approximation A/D and trimmed internal clock.

The LTC1606’s input range is an industry standard

±10V.

Maximum DC specs include

±2.0LSB INL and 16 bits no

missing codes over temperature. An external reference

can be used if greater accuracy over temperature is

needed.

The 90dB signal-to-noise ratio offers an improvement of

3dB over competing devices, and the RMS transition noise

is reduced (0.65LSB vs 1LSB) relative to competitive

parts.

The ADC has a microprocessor compatible, 16-bit or two

byte parallel output port. A convert start input and a data

ready signal (BUSY) ease connections to FIFOs, DSPs and

microprocessors.
