They are also designed to operate over a wide range of supply voltages: from standard ±15V operational amplifier supplies down to the single +5V supply used for IC logic. Their output is compatible with RTL-DTL and TTL as well as MOS circuits and can switch voltages up to +50V at output currents as high as 50mA.

This rating applies for ±15V supplies. The positive input voltage limit is 30V above the negative. The negative input voltage is equal to the negative supply voltage or 30V below the positive supply, whichever is less. 2. Pd is calculated with Tamb = +25°C, Tj = +150°C and Rthja = 100°C/W for the DIP8 package, and Rthja = 175°C/W for the SO-8 package. Table 2.

The offset voltage, offset current and bias current specifications apply for any supply voltage from a single +5V supply up to ±15V supplies. The offset voltages and offset currents given are the maximum values required to drive the output down to +1V or up to +14V with a 1mA load current. Thus, these parameters define an error band and take into account the worstcase of voltage gain and input impedance. 2. The response time specified is for a 100mV input step with 5mV overdrive. 5/14 Electrical characteristics LM111-LM211-LM311 6/14 LM111-LM211-LM311 Electrical characteristics 7/14 Electrical characteristics LM111-LM211-LM311 8/14 LM111-LM211-LM311 Typical application schematics 4 Typical application schematics 9/14 Package mechanical data LM111-LM211-LM311 5 Package mechanical data In order to meet environmental requirements, STMicroelectronics offers these devices in ECOPACK® packages.
