It is laser trimmed for low offset voltage and drift, greatly reducing the large errors common with LM324-type op amps. Input offset current is also trimmed to reduce errors in high impedance applications. The OPA1013 is characterized for operation at both +5V (single supply) and ±15V power supplies. When operated from a single supply, the input common-mode range includes ground and the output can swing to within 15mV of ground. Completely independent biasing networks eliminate interaction between the two amplifiers—even when one is used as a comparator. The OPA1013 is available in an 8-pin plastic DIP specified for the 0°C to +70°C temperature range. 3.3µA Simplified Circuit (Half of Dual) 3.3µA 7.5µA V+ 8 400Ω 0.9V 400Ω 2nd Gain Stage 22Ω Out 1, 7 In – 2, 6 In + 3, 5 22Ω V– 4 International Airport Industrial Park • Mailing Address: PO Box 11400 Tel: (520) 746-1111 • Twx: 910-952-1111 • Cable: BBRCORP • • Tucson, AZ 85734 • Street Address: 6730 S.

Follow good design practice by bypassing the power supplies close to the op amp pins. In most cases 0.1µF ceramic capacitors are adequate. SINGLE POWER SUPPLY OPERATION The OPA1013 is specified for operation from a single power supply. This means that linear operation continues with the input terminals at (or even somewhat below) ground potential. When used in a non-inverting amplifier, 0V input must produce 0V output. In practice, the output swing is limited to approximately 15mV above ground with no load. Output swing near ground can be optimized when the output load is connected to ground. If the output must sink current, the ability to swing near ground will be diminished. The output swings to within approximately 200mV of ground when sinking 1mA. INPUT PROTECTION The circuitry of the OPA1013 is protected against overload for input voltages ranging from the positive supply voltage to 5V below the negative supply voltage (below ground in single supply operation). No external protection circuitry is required, as it is with other common single-supply op amps. Furthermore, the OPA1013 is free from phase-reversal problems common with other single-supply op amps. When the inputs are driven below ground (or below the negative power supply), the output polarity remains correct. COMPARATOR OPERATION The OPA1013 functions well as a comparator, where high speed is not required. Sometimes, in fact, the low offset and docile characteristics of the OPA1013 may simplify the design of comparator circuitry. The two op amps in the OPA1013 use completely independent bias circuitry to avoid interaction when the inputs are over-driven. Driving one op amp into saturation will not affect the characteristics of the other amplifier. The outputs of the OPA1013 can drive one TTL load. Quiescent current remains stable when the inputs are overdriven. 0-4mA In + +VS R3 100Ω C1 0.001µF R4 500Ω 0-4mA Out 1/2 OPA1013 – N channel enhancement MOSFET Supertex, Siliconix, Motorola, etc. or 2 x 2N2222 R1 500Ω R2 50Ω To Ground or –VS FIGURE 1.
