D AC9331-16 Series D ata Converter Line 14, 15, and 16-Bit Linearity, Latched MD ACs FEATURES • • • • • • • • Up to 16-Bit Linearity Two Chip Construction Input Registers Low Power Ceramic 24-Pin DIP 2 and 4-quadrant M ultiplication Single-Supply Operation Low-Cost Low Power — CM OS proprietary monolithic devices in a unique circuit configuration yield the lowest power of any 16-Bit converter available. Tw o-Chip Construction — A n advanced monolithic device, combined with our own resistor networks are all that's needed in this converter. A utomatic wirebonding makes the most consistently superior assembly available. DESCRIPTION Input Storage Registers — Designed as two 8-Bit segments, the input registers provide data storage when latched, or " transparent" registers when unlatched. Data conversion can now be performed continuously or from stored data — " byte-sized" input segments provide compatibility with most data bus lines. The DA C9331-16 Series are true 16-Bit D/A converters manufactured with advanced proprietary monolithic devices and proven performance packaging technique. A single, unique monolithic chip contains switches, storage registers and other electronics for high resolution and low linearity error. A second, passive chip provides all the needed resistors for these multiplying D/A 's. Input storage registers are in two 8-Bit segments with independent latching — compatible with microprocessor data bus interfaces. It's a truly “ byte-sized” D/A input system. It combines 2- and 4-quadrant multiplying capability. TTL/DTL and CM OS compatibility; low power consumption (less than 60 mW ) and operation from a single supply, the DA C9331-16 Series offers exceptional performance/cost ratio. Outstanding features include: Reliability — A proven performer, the DA C9331-16 is packaged in a 24-pin ceramic double DIP for the utmost in reliability. Combined with our proprietary monolithic switches and automatic wirebonding, we've made the DA C9331 -16 Series the most reliable industrial converter to date. Reliability is further enhanced by batchprocessed. precision laser-trimmed resistor networks fabricated in our own facility. Networks are functionally trimmed and glass passivated to assure reliability under adverse environmental conditions. True 16-Bit Linearity —16-Bit (0.0008% ) linearity with 16-Bit resolution is now a reality. No other microcircuit converter does better. 14- and 15-Bit linearity versions available at lower cost. A dvanced designs, proven processes and continuous monitoring during all production operations by our quality control organization are combined with rigorous A QL screening to provide the most dependable, low cost D/A converter possible.

Using the internal R feedback with nulled external amplifier in a constant 25ºC ambient. (Offset doubles every 10ºC). 5. The DA C9331-16 Series is designed to be used only in those applications where the current output is virtual ground; i.e., the summing junction of an op amp in the inverting mode. The internal feedback resistor (R Feedback) must be used to achieve temperature tracking. See A PPLICA TIONS INFORM A TION for recommended circuit configurations. 6.
