17 / 19 page AD2S80A –16– APPLICATIONS Control Transformer The ratio multiplier of the AD2S80A can be used independently of the loop integrators as a control transformer. In this mode the resolver inputs θ are multiplied by a digital angle φ any differ- ence between φ and θ will be represented by the AC ERROR output as SIN ωt sin (θ–φ) or the DEMOD output as sin (θ–φ). To use the AD2S80A in this mode refer to the “Control Trans- former” application note. Dynamic Switching In applications where the user requires wide band response from the converter, for example 100 rpm to 6000 rpm, superior per- formance is achieved if the converters control characteristics are switched dynamically. This reduces velocity offset levels at low tracking rates. For more information on the technique refer to “Dynamic Resolution Switching Using the Variable Resolution Monolithic Resolver-to-Digital Converters.” OTHER PRODUCTS The AD2S82A is a monolithic, variable resolution 10-, 12-, 14- and 16-bit resolver-to-digital converter in a 44-terminal J-leaded PLCC package. In addition to the AD2S80A functions it has a VCO OUTPUT which is a measure of position within a LSB, and a COMPLEMENT Data Output. The AD2S81A is a low cost, monolithic, 12-bit resolver-to- digital converter in a 28-lead ceramic DIP package. REV. D |
