ELM45L58xA Bipolar Dual operational amplifier http://www.elm-tech.com ■General description ELM45L58xA is a dual bipolar op-amp using 4558 type circuit structure with improved low voltage operation and low power consumption. 1.0Vp-p output voltage swing is possible at ±1.5V power supply operation. Power current is 1.5mA(typ.). Maximun operating voltage is ±8V. GB product is 3MHz same as typical 4558 op-amp. ELM45L58 is assembled in SOP-8 and TSOT-28 small packages for small footprint. ■Features ■Application • • • • • • Battery-operated portable devices • Measurement equipment • Low voltage analog circuit 4558 Compatible operational amplifier Low voltage operation : 16V to 3V(±8V to ±1.5V) Constant current operation : Typ.1.5mA Unity gain bandwidth : Typ.3MHz Package : SOP-8, TSOT-28 ■Maximum absolute ratings Parameter Power supply voltage Input voltage Differential input voltage Power dissipation Operation temperature Storage temperature Symbol Vcc Vin Vid Pd Top Tstg Limit 18 18 ±18 300 -40 to +85 -55 to +125 Unit V V V mW °C °C ■Selection guide ELM45L58xA-x Symbol a Package b Product version c Taping direction D : SOP-8 L : TSOT-28 A S : Refer to PKG file N : Refer to PKG file ELM45L58 x A - x ↑ ↑ ↑ a b c ■Pin configuration SOP-8(TOP VIEW) Pin No. 1 2 3 4 5 6 7 8 Pin name OUTA IN-A IN+A GND IN+B IN-B OUTB VCC TSOT-28(TOP VIEW) Rev.1.0 3 - 1 ELM45L58xA Bipolar Dual operational amplifier http://www.elm-tech.com ■Electrical characteristics Parameter Input offset voltage Input offset current Input bias current Voltage gain Common-mode input voltage range Maximum output voltage swing Current consumption Slew rate Input noise voltage Unity gain bandwidth Symbol Vio Iio Iib Av Vcmr Vom Icc SR Vni GBW Condition RS≤10kΩ RL≥10kΩ Vout=0V(No load ) RL=2kΩ RS=1kΩ, f=30Hz to 30kHz Vcc=+5V, GND=-5V, Top=25°C Min.
