DAC suits digital calibration applications.

Press Release Summary:




Model LTC2600 octal, 16-bit VOUT digital-to-analog converter comes in 16-pin narrow SSOP package. Also available in 12-Bit and 14-Bit versions, units guarantee monotonic performance with Differential Non-Linearity of ±1LSBMAX that is critical in control loop applications. Devices consume 250 uA per DAC and drop to 44 nA per DAC in power-down mode. They deliver rail-to-rail voltage outputs over 2.5-5.5V supply range.



Original Press Release:



Octal 16-Bit DAC in Tiny SSOP-16 Package, Same Board Space as an SO-8



14-Bit and 12-Bit Versions Join the Existing Pin-Compatible 10-Bit and 8-Bit Families

MILPITAS, CA - May 9, 2003 - Linear Technology introduces the LTC2600, an octal 16-Bit VOUT DAC in a 16-pin narrow SSOP package. Alternative solutions require twice the board space of the LTC2600. Also available in 12-Bit and 14-Bit versions, these tiny DACs guarantee monotonic performance with Differential Non-Linearity (DNL) of ±1LSBMAX that is critical in control loop applications. The devices consume only 250uA per DAC and drop to 44nA per DAC in power-down mode. High resolution, small size and low power make these low cost octal DACs ideal for digital calibration, portable instrumentation and industrial process control applications.

The LTC2600 (16-Bit), LTC2610 (14-Bit) and LTC2620 (12-Bit) feature an easy to use interface and buffered rail-to-rail outputs for high density closed loop applications. A 3-wire serial interface controls each DAC simplifying transmission through isolation barriers or to remote locations. Each of the eight DACs can be simultaneously updated with a different input code. An asynchronous clear input clears the double-buffered input registers and sets the outputs to zero, easing system initialization and reset. The DACs deliver rail-to-rail voltage outputs over a wide 2.5V to 5.5V supply range. A full-scale transition on seven of the eight DACs causes less than 10uV change in the eighth DAC; this effectively eliminates crosstalk as a source of error.

The LTC2600 family is available in a 16-pin SSOP package and screened for both commercial and industrial temperature ranges. Pricing starts at $14.00 each for the LTC2600, $11.00 each for the LTC2610 and $7.75 each for the LTC2620 in 1,000-piece quantities.
