The LTC
2239 is a 10-bit 80Msps, low power 3V A/D
converter designed for digitizing high frequency, wide
dynamic range signals. The LTC2239 is perfect for de-
manding imaging and communications applications with
AC performance that includes 61.6dB SNR and 85dB
SFDR for signals well beyond the Nyquist frequency.
DC specs include
±0.1LSB INL (typ), ±0.1LSB DNL (typ)
and
±0.5LSB INL, ±0.5LSB DNL over temperature. The
transition noise is a low 0.08LSBRMS.
A single 3V supply allows low power operation. A separate
output supply allows the outputs to drive 0.5V to 3.6V
logic.
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.
