Low Noise 3V ADCs
The LTC
2238/LTC2237/LTC2236 are 10-bit 65Msps/
40Msps/25Msps, low power 3V A/D converters designed
for digitizing high frequency, wide dynamic range signals.
The LTC2238/LTC2237/LTC2236 are perfect for demand-
ing imaging and communications applications with AC
performance that includes 61.8dB SNR and 85dB SFDR
for signals at the Nyquist frequency.
DC specs include
±0.1LSB INL (typ), ±0.05LSB DNL (typ)
and
±0.5LSB INL, ±0.5LSB DNL over temperature. The
transition noise is a low 0.07LSBRMS.
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.
