Converters offer simultaneous sampling at 3 MSPS.

Press Release Summary:




Models LTC1407A and LTC1407 are 14-bit and 12-bit Analog-to-Digital Converters with 2 simultaneous sampling inputs. Ten-pin MSOP package allows design of compact high-speed data acquisition systems. Powered from single 3 V supply with power dissipation of 12 mW, Model LTC1407A achieves 73.5 dB SINAD and guarantees 14-bit no missing codes. When device is not converting, power dissipation can be reduced to 3.3 mW in NAP mode, with 2.5 V reference remaining active.

Tiny 2-Channel, 14-bit ADC Offers Simultaneous Sampling at 3Msps



Enables Compact High-Speed Data Acquisition Systems

MILPITAS, CA - January 5, 2004 - Linear Technology introduces the LTC1407A and LTC1407, 14-bit and 12-bit, 3Msps Analog to Digital Converter (ADC) with two simultaneous sampling inputs. These high speed serial ADC 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 device achieves 73.5dB SINAD and guarantees 14-bit no missing codes. The small size in combination with high speed and simultaneous sampling make the LTC1407 the ideal choice for medical applications, instrumentation, multiphase motor control and narrowband I & Q demodulation applications.

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 6uW with everything powered down in the SLEEP mode. The two conversion results are delivered sequentially to high speed DSP serial ports via a 3-wire SPI interface. These features support new smaller, lower power designs for simultaneous sampling applications.

The LTC1407A and LTC1407 are available in the commercial and industrial temperature ranges. Pricing begins at $7.00 each for the LTC1407A and $4.00 each for the LTC1407 in 1,000-piece quantities.
