DESCRIPTION

The HS 3860 is a 12-Bit digital-to-analog converter packaged in a hermetically sealed 24-pin double- width, dual-in-line package. The D/A is constructed using hybrid microcircuit technology and includes a precision thin-film network, laser-trimmed to produce a high linearity, high accuracy converter, stable over a wide temperature range. Errors in linearity and accuracy are specified at room temperature as well as operating temperature extremes for both military and commercial products. The HS 3860 includes an internal precision reference supply, a fast output amplifier for minimum settling time, and input registers for easier microprocessor interface. M IL-STD-883 Rev. C, Level B screening and processing is available in the “B” grade device. Operating temperature range for the HS 3860B is – 55ºC to +125ºC. 1 2 3 4 5 6 7 8 9 10 11 12 REGISTER ENA BLE

Case Style 24 Pin DIP. Ceramic NOTES 1. The analog output follows the digital input when Register Enable is a logic “0”. The analog output is constant when the Register Enable is a logic “1”. 2. SatCon guarantees and tests maximum Linearity Error at the extremes of the operating temperature and at room temperature. ±1/2 LSB Linearity Error guarantees monotonicity and differential linearity of ±1 LSB. and 1 LSB is 4.88mV . 5. A bsolute A ccuracy Error includes linearity, gain, offset and all other errors and is specified without the use of adjustments. 6. Commercial M odels are specified over a temperature range of 0ºCto+70ºC.
