Overview
a FEATURES Complete Current Output Converter High Stability Buried Zener Reference Laser Trimmed to High Accuracy (1/4 LSB Max Error, AD561K, T) Trimmed Output Application Resistors for 0 V to +10 V, ؎5 V Ranges Fast Settling – 250 ns to 1/2 LSB Guaranteed Monotonicity Over Full Operating Temperature Range TTL/DTL and CMOS Compatible (Positive True Logic) Single Chip Monolithic Construction Available in Chip Form MlL-STD-883-Compliant Versions Available PRODUCT DESCRIPTION Low Cost 10-Bit Monolithic D/A Converter AD561 FUNCTIONAL BLOCK DIAGRAM TO-116 The AD561 is an integrated circuit 10-bit digital-to-analog converter combined with a high stability voltage reference fabricated on a single monolithic chip.
Using ten precision highspeed current-steering switches, a control amplifier, voltage reference, and laser-trimmed thin-film SiCr resistor network, the device produces a fast, accurate analog output current.
Laser trimmed output application resistors are also included to facilitate accurate, stable current-to-voltage conversion; they are trimmed to 0.
1% accuracy, thus eliminating external trimmers in many situations.
Several important technologies combine to make the AD561 the most accurate and most stable 10-bit DAC available.
The low temperature coefficient, high stability thin-film network is trimmed at the wafer level by a fine resolution laser system to 0.
01% typical linearity.
This results in an accuracy specification of ± 1/4 LSB max for the K and T versions, and 1/2 LSB max for the J and S versions.
The AD561 also incorporates a low noise, high stability subsurface zener diode to produce a reference voltage with excellent long term stability and temperature cycle characteristics, which challenge the best discrete Zener references.
A temperature compensation circuit is laser-trimmed to allow custom correction of the temperature coefficient of each device.
This results in a typical full-scale temperature coefficient of 15 ppm/°C; the TC is tested and guara...
