Description

The AK2710 is a 16-bit, high speed oversampled

digital-to-analog converter optimized for waveform

reconstruction applications requiring high dynamic

range. Glitches that are characteristic of Nyquist rate

DACs are avoided by use of an over-sampled, multi-

bit sigma-delta architecture. The AK2710 is

inband images eliminating the need for complex

external analog smoothing filters. Additional out-of-

band filtering is provided after the sigma-delta DAC

The on-chip reference and reference buffer amplifier

are configured for maximum accuracy and flexibility.

manufactured on an advanced submicron analog

process. High dynamic range is achieved by the use

of proprietary multi bit delta sigma techniques.

Phase-Lock-Loop clock multiplier provides the

necessary synchronized 16fs clock to support the

over-sampled DAC. An external synchronous clock

can also be used.

The AK2710 is a switched capacitor DAC, with a

nominal full scale differential output of 4 V with a

common-mode output level of 2.5V.

The AK2710 operates on a single +5 V analog supply

and +5 V/ +3 V digital supply, typically consuming

300mW. The AK2710 is available in a 44-lead LQFP

package and is specified to operate from -40 to 85C.

The on-chip interpolation filter suppresses original
