Am6070

The Am6070 is a kind of monolithic companding digital-to-analog (D/A) converter which achieves a 72 dB dynamic range equivalent to that achieved by a 12-bit converter.The typical applications include digital audio recording,servo-moto controls,electromechanical positioning,voice synthesis,secure communications,microprocessor controlled sound and voice systems,log sweep generators and various data acquisition systems.

There are some distinctive characteristics of Am6070.First is tested to -255 companding law.The second is absolute accuracy specified-includes all errors over temperature range.Then is settling time 300 ns typical.Next is ideal for multiplexed PCM,audio and 8-bit  -P systems.The fifth is output dynamic range of 72 dB.The sixth is improved pin-for-pin replacement for DAC-76.The seventh is microprocessor controlled operations.The eighth is multiplying operation and negligible output noise.The ninth is monotonicity guaranteed over entire dynamic range.The tenth is low power consumption and wide output voltage compliance.The eleventh is 12-bit accuracy and resolution around zero.The last one is sign plus 12-bit range with sign plus 7-bit coding.

What comes next is about the absolute maximum ratings of Am6070.The V⁺ supply to V^- supply is 36 V.The VLC swing is from V^-+8 V to V^-+36 V.The reference inputs is from V^- to V⁺.The reference input differential voltage is ±18 V.The reference input current is 1.25 mA.The logic inputs is from V^-+18 V to V^-+36 V.The operating temperature is from -55 to +125 for MIL grade and is from 0 to +70 for COM'L grade.The storage temperature is from -65 to +150.The power dissipation is 500 mW at T_A100 and derate at 10 mW/ for T_A>100.The lead soldering temperature is 300 (60 sec).
