The AD8519 brings precision and bandwidth to the SC70 and SOT-23 packages. The low supply current makes the AD8519/AD8529 ideal for batterypowered applications. The rail-to-rail output swing of the AD8519/AD8529 is larger than standard video op amps, making them useful in applications that require greater dynamic range than standard video op amps. The 2.9 V/μs slew rate makes the AD8519/AD8529 a good match for driving ASIC inputs such as voice codecs. The small SC70 package makes it possible to place the AD8519 next to sensors, reducing external noise pickup. The AD8519/AD8529 is specified over the extended industrial (−40°C to +125°C) temperature range. The AD8519 is available in 5-lead SC70 and 5-lead SOT-23 packages, and an 8-lead SOIC surface-mount package. The AD8529 is available in 8-lead SOIC and 8-lead MSOP packages. Rev.

Large Signal Transient Response Rev. D | Page 11 of 16 AD8519/AD8529 APPLICATIONS INFORMATION R4 10kΩ The maximum power that can be safely dissipated by the AD8519/AD8529 is limited by the associated rise in junction temperature. The maximum safe junction temperature is 150°C for these plastic packages. If this maximum is momentarily exceeded, proper circuit operation is restored as soon as the die temperature is reduced. Operating the product in an overheated condition for an extended period can result in permanent damage to the device. VIN D1 1N914 The operation of the basic circuit (shown in Figure 23) should be examined before considering the slew rate further. U1 is set up to have two states of operation. D1 and D2 diodes switch the output between the two states. State one is an inverter with a gain of +1, and state two is a simple unity gain buffer where the output is equal to the value of the virtual ground. The virtual ground is the potential present at the noninverting node of the U1. State one is active when VIN is larger than the virtual ground. D2 is on in this condition. If VIN drops below virtual ground, D2 turns off and D1 turns on. This causes the output of U1 to simply buffer the virtual ground and this configuration is state two. Therefore, the function of U1, which results from these two states of operation, is a half-wave inverter. The U2 function takes the inverted half wave at a gain of two and sums it into the original VIN wave, which outputs a rectified full wave. VOUT = VIN − 2 V IN −1 < 0 This type of rectifier can be very precise if the following electrical parameters are adhered to: • All passive components should be of tight tolerance, 1% for resistors and 5% for capacitors. If the application circuit requires high impedance (that is, direct sensor interface), then an FET amplifier is a better choice than the AD8519. An amp such as the AD8519, which has a great slew rate specification, yields the best result because the circuit involves switching. R3 4.99kΩ D2 1N914 R5 10kΩ R6 5kΩ VOUT U2 AD8519 AD8519 VIRTUAL GROUND = Slew rate is probably the most underestimated parameter when designing a precision rectifier. Yet without a good slew rate, large glitches are generated during the period when both diodes are off. • NODE A U1 PRECISION FULL-WAVE RECTIFIER • R2 10kΩ R1 10kΩ R7 3.32kΩ VCC 2 01756-023 MAXIMUM POWER DISSIPATION Figure 23. Precision Full-Wave Rectifier Switching glitches are caused when D1 and D2 are both momentarily off. This condition occurs every time the input signal is equal to the virtual ground potential. When this condition occurs, the U1 stage is taken out of the VOUT equation and VOUT is equal to VIN × R5 × (R4 || R1 + R2 + R3). Note that Node A should be VIN inverted or virtual ground, but in this condition, Node A is simply tracking VIN. Given a sine wave input centered around virtual ground, glitches are generated at the sharp negative peaks of the rectified sine wave. If the glitches are hard to notice on an oscilloscope, raise the frequency of the sine wave until they become apparent. The size of the glitches is proportional to the input frequency, the diode turn-on potential (0.2 V or 0.65 V), and the slew rate of the op amp. R6 and R7 are both necessary to limit the amount of bias current related voltage offset. Unfortunately, there is no perfect value for R6 because the impedance at the inverting node is altered as D1 and D2 switch. Therefore, there is also some unresolved bias current related offset. To minimize this offset, use lower value resistors or choose an FET amplifier if the optimized offset is still intolerable. The AD8519 offers a unique combination of speed vs. power ratio at 2.7 V single supply, small size (SC70 and SOT-23), and low noise that makes it an ideal choice for most high volume and high precision rectifier circuits. Rev. D | Page 12 of 16 AD8519/AD8529 TWO-ELEMENT VARYING BRIDGE AMPLIFIER 10× MICROPHONE PREAMP MEETS PC99 SPECIFICATIONS This circuit, while lacking a unique topology, is anything but featureless when an AD8519 is used as the op amp. This preamp gives 20 dB gain over a frequency range of 20 Hz to 20 kHz and is fully PC99 compliant in all parameters including THD + N, dynamic range, frequency range, amplitude range, and crosstalk. Not only does this preamp comply with the PC99 specifications, it far surpasses them. In fact, when the input noise is 120 dB, this preamp has a VOUT noise of around 100 dB, which is suitable for most professional 20-bit audio systems. At 120 dB THD + N in unity gain, the AD8519 is suitable for 24-bit professional audio systems. In other words, the AD8519 will not be the limiting performance factor in audio systems despite its small size and low cost. Slew rate related distortion is not present at the lower voltages because the AD8519 is so fast at 2.1 V/μs. A general rule of thumb for determining the necessary slew rate for an audio system is to take the maximum output voltage range of the device, given the design’s power rails, and divide by two. In Figure 24, the power rails are 2.7 V and the output is rail-to-rail. Enter these numbers into the equation: 2.7/2 = 1.35 V, and the minimum ideal slew rate is 1.35 V/μs. There are a host of bridge configurations available to designers. For a complete analysis, look at the ubiquitous bridge and its different forms. Refer to the 1992 Amplifier Applications Guide 1 . Figure 25 is a schematic of a two-element varying bridge. This configuration is commonly found in pressure and flow transducers. With a two-element varying bridge, the signal is 2× as compared to a single-element varying bridge. The advantages of this type of bridge are gain setting range and single-supply application. Negative characteristics are nonlinear operation and required R matching. Given these sets of conditions, requirements, and characteristics, the AD8519 can be successfully used in this configuration because of its rail-to-rail output and low offset. Perhaps the greatest benefits of the AD8519, when used in the bridge configuration, are the advantages it can bring when placed in a remote bridge sensor. For example, the tiny SC70 and SOT-23 packages reduce the overall sensor size; low power allows for remote powering via batteries or solar cells, high output current drive to drive a long cable; and 2.7 V operation for two-cell operation. 2.7V RF C1 1µF MIC IN 1 30.9kΩ 2.7V CODEC LINE IN OR MIC IN 3.09kΩ 1nF NPO AD8519 46.4kΩ 93.1kΩ R AD8519 RF Adolfo Garcia and James Wong, Chapter 2, 1992, Amplifier Applications Guide. 48kΩ 2.7V 10µF ELECT 01756-024 1kΩ R Figure 25.
