C Processing Available DESCRIPTION The HS 3020 is an 8-Bit Digital-to-Analog Converter. It contains an internal reference, an input register and an output amplifier. It is packaged in a ceramic 18-pin DIP which is hermetically- sealed. The HS 3020's hybrid construction utilizes a precision network, a low drift reference, an input register and a fast set- tling output amplifier. Hybrid Systems guarantees linearity and accuracy not only at room temperature but also at the extremes of the operating range of 55C to + 125C.
