MILPITAS, CA February 21, 2008 Linear Technology Corporation introduces 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 unipolar or bipolar ranges. Operating from a single 5V supply, the LTC2309 draws just 1.5mW at a 1ksps throughput rate and only 35uW in shutdown mode. Packaged in a tiny 4mm x 4mm QFN-24 with internal reference, the LTC2309 is a great fit for portable instrumentation and space-constrained designs using I2C. |
