... AD8541/AD8542/AD8544 THEORY OF OPERATION NOTES ON THE AD854x AMPLIFIERS The AD8541/AD8542/AD8544 amplifiers are improved performance, general-purpose operational amplifiers. Performance has been improved over previous amplifiers in several ways. Lower Supply Current for 1 MHz Gain Bandwidth The AD854x series typically uses 45 μA of current per amplifier. ...
Page 13
... The AD854x have very high open-loop gain (especially with a supply voltage below 4 V), which makes it useful for active filters of all types. For example, Figure 35 illustrates the AD8542 in the classic twin-T notch filter design. The twin-T notch is desired for simplicity, low output impedance, and minimal use of op amps ...
Page 14
... AD8541/AD8542/AD8544 PHOTODIODE APPLICATION The AD854x family has very high impedance with an input bias current typically around 4 pA. This characteristic allows the AD854x op amps to be used in photodiode applications and other applications that require high input impedance. Note that the AD854x has significant voltage offset that can be removed by capacitive coupling or software calibration ...
