Dual 14-Bit, 80Msps
Low Power 3V ADC
The LTC®2299 is a 14-bit 80Msps, low power dual 3V
A/D converter designed for digitizing high frequency, wide
dynamic range signals. The LTC2299 is perfect for
demanding imaging and communications applications
with AC performance that includes 73dB SNR and 90dB
SFDR for signals well beyond the Nyquist frequency.
DC specs include ±1.2LSB INL (typ), ±0.5LSB DNL (typ)
and ±5LSB INL, ±1LSB DNL over temperature. The transi-
tion noise is a low 1.2LSBRMS.
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.
