... Process Control Equipment PC Peripherals GENERAL DESCRIPTION The DAC8562 is a complete, parallel input, 12-bit, voltage out- put DAC designed to operate from a single +5 volt supply. Built using a CBCMOS process, these monolithic DACs offer the user low cost, and ease-of-use in +5 volt only systems. ...

... V voltage levels. The graph in Figure 9 shows the effect on to- OL tal DAC8562 supply current as a function of the actual value of input logic voltage. Consequently for optimum dissipation use of CMOS logic versus TTL provides minimal dissipation in the static state lowest standby dissipation of 600 A with power supply. ...

... One advantage of the rail-to-rail output amplifier used in the DAC8562 is the wide range of usable supply voltage. The part is fully specified and tested over temperature for operation from +4. +5. reduced linearity and source current ca- pability near full scale can be tolerated, operation of the DAC8562 is possible down to +4 ...

... To protect devices that interface to both digital and analog parts of the sys- tem, such as the DAC8562 recommended that the com- mon ground tie points be provided at each such device. If only one system ground can be connected directly to the DAC8562, it recommended that the analog common be used. If the system’ ...

... V supply, a single +5 V supply may not be available in many applications. Since the DAC8562 consumes no more than 6 mA, maximum, then an integrated voltage reference, such as the REF02, can be used as the DAC8562 +5 V supply. The configuration of the circuit is shown in Figure 31. Notice that the reference’s output voltage requires no trimming because of the REF02’ ...

... AGND 12 10 Bipolar Output Operation Although the DAC8562 has been designed for single supply op- eration, bipolar operation is achievable using the circuit illus- trated in Figure 33. The circuit uses a single supply, rail-to-rail OP295 op amp and the DAC’s internal +2.5 V reference to gen- erate the –2.5 V reference required to level-shift the DAC out- put voltage. The circuit has been configured to provide an output voltage in the range – ...

... Figure 36. Generating a –5 V Supply When Only + +15 V Are Available Audio Volume Control The DAC8562 is well suited to control digitally the gain or attenuation of a voltage controlled amplifiers. In professional audio mixing consoles, music synthesizers, and other audio proces- sors, VCAs, such as the SSM2018, adjust audio channel gain and attenuation from front panel potentiometers ...

... A High-Compliance, Digitally Controlled Precision Current Source The circuit in Figure 38 shows the DAC8562 controlling a high-compliance, precision current source using an AMP05 in- strumentation amplifier. The AMP05’s reference pin becomes the input, and the “old” inputs now monitor the voltage across a precision current sense resistor, R ...

... DAC8562 Decoding Multiple DAC8562s The CE function of the DAC8562 can be used in applications to decode a number of DACs. In this application, all DACs re- ceive the same input data; however, only one of the DACs’ CE input is asserted to transfer its parallel input register contents into the DAC. In this circuit, shown in Figure 40, the CE tim- ing is generated by a 74HC139 decoder and should follow the DAC8562’ ...
