The improved performance

OP200 is the first OP77 accuracy performance performance The single -piece dual operation amplifier. OP200 uses industrial standard 8-lead pins, combining the accuracy, space and cost savings provided by the dual amplifier.

OP200 has a very low input offset voltage, less than 75 μV, and drifting below 0.5 μV/° C. It is guaranteed to be within the entire military temperature range. OP200's open -loop gain under 10K more than 50,00000,000; input bias current is lower than 2NA; CMR exceeds 120dB, and PSRR is lower than 1.8 μV/V. The Qina ZAP is finely tone to achieve extremely low OP200 input bias voltage and eliminates the needs of bias traction.

The power consumption of OP200 is very low, and the power supply current of each amplifier is less than 725 μA. The total current of the dual OP200 is less than half of the single OP07, but the OP200 has significantly improved the OP200 than the industry standard operational amplifier. The voltage noise density of OP200 is 11nv/√Hz. At 1kHz, it is half of most competitive devices.

OP200 is compatible with OP221, LM158, MC1458/1558 and LT1013.

OP200 is an ideal choice for requiring multiple precision computing amplifiers and low power consumption.

For four -precision computing amplifier, see OP400.

pin connection

ApplicationOrder information OP200 is essentially stable under all gains, and can drive large capacitors loads without oscillation. Nevertheless, it is strongly recommended to maintain good supply. Appropriate power decoupling can reduce the problem of the noise of the power cord and improve the capacitor load driving capacity of OP200. Application

Dual low -power meter amplifier

FIG. 4 shows the dual -instrument amplifier with a power consumption of less than 33MW. The gain ratio between 100 and 100 bits between 200 and 100 bits is better than 100 to 100 bits. The gain is greater than 1000 cmrr u003d 115. In the military temperature range, the offset voltage drifting is usually 0.2 μV/° C, which is equivalent to the best single -chip instrument amplifier. The bandwidth of the low -power meter amplifier is the gain function, as shown below:

The output signal is related to the reference input. The reference input is usually connected to the analog ground. If necessary, refer to the input to displace the output from -10 V to +10 V.

Precision absolute value placed large device The circuit in FIG. 5 is a precision absolute value of the input impedance of 10 m OP200's high -gain and low TCVO guarantees the precise operation of the micro -input signal. In this circuit, input always appears as a co -mode signal on the operation amplifier. OP200's CMR is more than 120dB, and the error is less than 2PPM.
