LTC2290
Dual 12-Bit, 10Msps Low Power 3V ADC
DESCRIPTIO
The LTC®2290 is a 12-bit 10Msps, low power dual 3V A/D converter designed for digitizing high frequency, wide dynamic range signals. The LTC2290 is perfect for demanding imaging and communications applications with AC performance that includes 71.3dB SNR and 90dB SFDR for signals well beyond 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. An optional multiplexer allows both channels to share a digital output bus.
