Dual 14-Bit, 65/40/25Msps
Low Power 3V ADCs
The LTC
2298/LTC2297/LTC2296 are 14-bit 65Msps/
40Msps/25Msps, low power dual 3V A/D converters de-
signed for digitizing high frequency, wide dynamic range
signals. The LTC2298/LTC2297/LTC2296 are perfect for
demanding imaging and communications applications
with AC performance that includes 74.3dB SNR and 90dB
SFDR for signals at 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.
