APPLICATIONS
The OP400 is inherently stable at all gains and is capable of driving large capacitive loads without oscillating. Nonetheless, good supply decoupling is highly recommended. Proper supply decoupling reduces problems caused by supply line noise and improves the capacitive load-driving capability of the OP400. Total supply current can be reduced by connecting the inputs of an unused amplifier to V−. This turns the amplifier off, lowering the total supply current. DUAL LOW POWER INSTRUMENTATION AMPLIFIER A dual instrumentation amplifier that consumes less than 33 mW of power per channel is shown in Figure 30. The linear- ity of the instrumentation amplifier exceeds 16 bits in gains of 5 to 200 and is better than 14 bits in gains from 200 to 1000. CMRR is above 115 dB (G = 1000). Offset voltage drift is typically 0.4 μV/°C over the military temperature range, which is comparable to the best monolithic instrumentation amplifiers. The bandwidth of the low power instrumentation amplifier is a function of gain and is shown in Table 6. The output signal is specified with respect to the reference input, which is normally connected to analog ground. The reference input can be used to offset the output from −10 V to +10 V if required.
