16-Bit, 105Msps Low-Noise ADC Achieves 81.2dB SNR at Half the Power 1200mW
Linear Technology has introduced the LTC2217, a low noise, high performance 16-bit, 105Msps Analog to Digital Converter (ADC) with 81.2dBFS Signal-to-Noise Ratio (SNR) and 100dBc Spurious Free Dynamic Range (SFDR). Ultra-low jitter helps maintain the high SNR at high input frequencies, yielding 80.4dBFS SNR at 70MHz, while the high linearity
12-Bit, I2C SAR ADC Measures Eight Inputs & Dissipates Only 1.5mW
Linear Technology has introduced the LTC2309, a 12-bit analog-to-digital converter (ADC) that communicates via an I2C-compatible 2-wire interface with 14ksps throughput rate. This flexible ADC features an 8-channel integrated multiplexer to measure eight single-ended input channels, four differential channels, or combinations of both. The input channels are software selectable for
