1 standaed ics dual high slew rate, low noise operational amplifier BA15218 / BA15218f / BA15218n the BA15218, BA15218f, and BA15218n are monolithic ics with two built-in low-noise, low-distortion operational amplifiers featuring internal phase compensation. either a dual or single power supply can be driven, and these products can be driven by a digital system 5v single power supply. the following packages are available: 8-pin dip (BA15218), 8-pin sop (BA15218f), and 8-pin sip (BA15218n). 1) low-voltage operation and single power supply drive enabled. (single power supply: 4 to 32v, dual power supply: ? to ?6v) 2) low noise level. (vn = 1.0 m v rms typ. : riaa) 3) high slew rate. (sr = 3v / m s, gbw = 10mhz typ.) 4) low offset voltage. (v io = 0.5mv typ.) 5) high gain and low distortion. (g vo = 110db, thd = 0.0015%) 6) pin connections are the same as with standard dual operational amplifiers, and outstanding characteris- tics make these products compatible with the 4558 and 4560 models. block diagram + + 1 2 3 4 8 7 6 5 out1 ?n1 + in1 v ee v cc out2 ?n2 + in2 1ch 2ch + + 1 out1 2 ?in1 3 + in1 4 v ee 5 + in2 6 ?in2 7 out2 8 v cc 2ch 1ch BA15218 / BA15218f BA15218n features
