12-bit, 8-channel A/D converter offers throughput rates up to 500ksps

Milpitas, Calif.—Linear Technology Corp. has introduced the LTC2308, a 12-bit A/D converter that measures eight single-ended input channels, four differential input channels, or combinations of both for digitizing multiple data acquisition signals with a single chip.

The LTC2308 features an internal 8-channel multiplexer and communicates via an SPI-compatible serial interface at throughput rates up to 500ksps. With the combination of an internal reference and a tiny 4mm x 4mm QFN-24 package, the LTC2308 provides a high level of integration to reduce board area and total system cost, making it suitable for portable instruments and space-constrained designs.

The LTC2308 operates from a single 5V supply, drawing 17mW at the 500ksps throughput rate. Power dissipation can be further decreased with two shutdown modes. Nap mode reduces the power to 1.15mW at 1ksps, and sleep mode shuts down all internal circuitry and reduces the power to 35µW.

Pricing: Begins at $2.95 for 1,000-piece quantities.
Availability: Today in both commercial and industrial temperature grades.
