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.
