DESCRIPTION
12-Bit, 65/40/25Msps
Low Power 3V ADCs
The LTC
2228/LTC2227/LTC2226 are 12-bit 65Msps/
40Msps/25Msps, low power 3V A/D converters designed
for digitizing high frequency, wide dynamic range signals.
The LTC2228/LTC2227/LTC2226 are perfect for demand-
ing imaging and communications applications with AC
performance that includes 71.3dB SNR and 90dB SFDR
for signals at the Nyquist frequency.
DC specs include ±0.3LSB INL (typ), ±0.15LSB DNL (typ)
and no missing codes over temperature. The transition
noise is a low 0.25LSBRMS.
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 performance
at full speed for a wide range of clock duty cycles.
