The parts use a patented trimming technique Figure 4. 14-Lead TSSOP (RU-14) that achieves superior precision without laser trimming. The AD8615/AD8616/ AD8618 are fully specified to operate from OUT A 1 14 OUT D 2.7 V to 5 V single supplies. IN A 2 13 IN D +IN A 3 12 +IN D AD8618 The combination of >20 MHz bandwidth, low offset, low noise, V+ 4 11 V TOP VIEW (Not to Scale) and low input bias current makes these amplifiers useful in a +IN B 5 10 +IN C IN B 6 9 IN C wide variety of applications. Filters, integrators, photodiode OUT B 7 8 OUT C amplifiers, and high impedance sensors all benefit from the combination of performance features. AC applications benefit from Figure 5. 14-Lead SOIC (R-14) the wide bandwidth and low distortion. The AD8615/AD8616/ AD8618 offer the highest output drive capability of the DigiTrim The AD8615/AD8616/AD8618 are specified over the extended family, which is excellent for audio line drivers and other low industrial temperature range (40C to +125C). The AD8615 impedance applications. is available in 5-lead TSOT-23 package. The AD8616 is available Applications for the parts include portable and low powered in 8-lead MSOP and narrow SOIC surface-mount packages the instrumentation, audio amplification for portable devices, MSOP version is available in tape and reel only. The AD8618 is portable phone headsets, bar code scanners, and multipole available in 14-lead SOIC and TSSOP packages. filters. The ability to swing rail-to-rail at both the input and output enables designers to buffer CMOS ADCs, DACs, ASICs, and other wide output swing devices in single-supply systems. Rev.
