11 / 12 page AD394 Rev. A | Page 11 of 12 OR’ed with LED indicators as shown. The test limits for each comparator are programmed by the AD394 VOUT2 and VOUT3 outputs. When the output of the device under testing is within the limits, both comparators are off and D1 lights. If the output is above or below the limits, either D4 or D5 lights. AD394 as a Multiplier and Attenuator So far, it has been assumed that the reference voltage VREFIN is fixed. In fact, VREFIN can be any voltage within the range of −11 V < VREFIN < +11 V. It can be negative, positive, sinusoidal, or whatever the user prefers. This leads to the name “multiplying D/A converters” because the output voltage, VOUT, is propor- tional to the product of the digital input word and the voltage at the VREFIN terminal. () () () 4095 D 0 4096 D V 1 V REFIN OUT < < − = D is the fractional binary value of the digital word applied to the converter. The AD394 multiplies the digital input value by the analog input voltage at VREFIN for any value of VREFIN up to 22 V p-p. This in itself is a powerful tool. Applications requiring precision multiplication with minimal zero offset and very low distortion should consider the AD394 as a candidate. One pop- ular use for the AD394 is as an audio frequency attenuator. The audio signal is applied to the VREFIN input and the attenuation code is applied to the DAC; the output voltage is the product of the two—an attenuated version of the input. The maximum attenuation range obtainable utilizing 12 bits is 4096:1 or 72 dB. Figure 16. AD394 as a Multiplier or Attenuator |
