LTC1606
1606fa
16-Bit, 250ksps,
Single Supply ADC
The LTC
®
1606 is a 250ksps, sampling 16-bit A/D con-
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.
