LTC2297 - Dual 14-Bit, 65/40/25Msps Low Power 3V ADCs
LTC2298/LTC2297/LTC2296 - Dual 14-Bit, 65/40/25Msps Low Power 3V ADCs - Linear Technology（凌力尔特）
功能描述
The LTC2298/LTC2297/LTC2296 are 14-bit 65Msps/40Msps/25Msps, low power dual 3V A/D converters designed 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 74dB SNR and 85dB SFDR for signals well beyond 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 3.3V 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 performance at full speed for a wide range of clock duty cycles.
