Linear Technology Corp. (LTC, Milpitas, CA) introduced the LTC1407A and LTC1407, 14-bit and 12-bit, 3Msps analog-to-digital converter with two simultaneous sampling inputs. The high-speed, serial converters are available in a 10-pin MSOP package, less than half the size of an SO-8, allowing the design of compact high-speed data acquisition systems.
The LTC1407A is powered from a single 3V supply and power dissipation is typically 12mW. When the device is not converting, power dissipation can be reduced to 3.3mW in the NAP mode, with the onboard 2.5V reference remaining active, and 6µW with everything powered down in the SLEEP mode. The two conversion results are delivered sequentially to high-speed DSP serial ports via a three-wire SPI interface.
The LTC1407A and LTC1407 are available in the commercial and industrial temperature ranges. Pricing begins at $7 each for the LTC1407A, and $4 each for the LTC1407, both in 1,000-piece quantities.
