LTC2295
Dual 14-Bit, 10Msps
Low Power 3V ADC
DESCRIPTIO
The LTC®2295 is a 14-bit 10Msps, low power dual 3V
A/D converter designed for digitizing high frequency, wide
dynamic range signals. The LTC2295 is perfect for
demanding imaging and communications applications
with AC performance that includes 74.4dB SNR and 90dB
SFDR for signals well beyond the Nyquist frequency.
DC specs include ±1.2LSB INL (typ), ±0.5LSB DNL (typ)
and no missing codes over temperature. The transition
noise is a low 1LSBRMS.
A single 3V supply allows low power operation. A separate
output supply allows the outputs to drive 0.5V to 3.6V
logic. An optional multiplexer allows both channels to
share a digital output bus.
A single-ended CLK input controls converter operation. An
optional clock duty cycle stabilizer allows high perfor-
mance at full speed for a wide range of clock duty cycles.
