Precision performance no longer has to be sacrificed to obtain the space and cost savings offered by quad amplifiers. The OP400 features an extremely low input offset voltage of less than 150 mV with a drift of under 1.2 mV/∞C, guaranteed over the full military temperature range. Open-loop gain of the OP400 is over 5,000,000 into a 10 kW load, input bias current is under 3 nA, CMR is above 120 dB, and PSRR is below 1.8 mV/V. On-chip zener-zap trimming is used to achieve the low input offset voltage of the OP400 and eliminates the need for offset nulling. The OP400 conforms to the industry-standard quad pinout which does not have null terminals. The OP400 features low power consumption, drawing less than 725 mA per amplifier. The total current drawn by this quad amplifier is less than that of a single OP07, yet the OP400 offers significant improvements over this industry standard op amp. Voltage noise density of the OP400 is a low 11 nV/÷Hz at 10 Hz, which is half that of most competitive devices. The OP400 is pin-compatible with the LM148, HA4741, RM4156, and LT1014 operational amplifiers and can be used to upgrade systems using these devices. The OP400 is an ideal choice for applications requiring multiple precision operational amplifiers and where low power consumption is critical. Figure 1.

Consult factory to negotiate specifications based on dice lot qualification through sample lot assembly and testing. CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the OP400 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality. WARNING! ESD SENSITIVE DEVICE – 4– REV.

Gain Bandwidth Gain 5 10 100 1000 Bandwidth 150 kHz 67 kHz 7.5 kHz 500 Hz 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. Figure 3. Burn-In Circuit APPLICATIONS INFORMATION 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. APPLICATIONS Dual Low-Power Instrumentation Amplifier A dual instrumentation amplifier that consumes less than 33 mW of power per channel is shown in Figure 1. The linearity 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 mV/∞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 I. Figure 4. Dual Low-Power Instrumentation Amplifier – 8– REV. A OP400 Figure 5. Bipolar Current Transmitter BIPOLAR CURRENT TRANSMITTER In the circuit of Figure 5, which is an extension of the standard three op amp instrumentation amplifier, the output current is proportional to the differential input voltage. Maximum output current is ± 5 mA with voltage compliance equal to ± 10 V when using ± 15 V supplies. Output impedance of the current transmitter exceeds 3 MW and linearity is better than 16 bits with gain set for a full scale input of ± 100 mV. DIFFERENTIAL OUTPUT INSTRUMENTATION AMPLIFIER The output voltage swing of a single-ended instrumentation amplifier is limited by the supplies, normally at ± 15 V, to a maximum of 24 V p-p. The differential output instrumentation amplifier of Figure 6 can provide an output voltage swing of 48 V p-p when operated with ± 15 V supplies. The extended output swing is due to the opposite polarity of the outputs. Both outputs will swing 24 V p-p but with opposite polarity, for a total output voltage swing of 48 V p-p. The reference input can be used to set a common-mode output voltage over the range ± 10 V. PSRR of the amplifier is less than 1 mV/V with CMRR (G = 1000) better than 115 dB. Offset voltage drift is typically 0.4 mV/∞C over the military temperature range. Figure 6. Differential Output Instrumentation Amplifier REV. A –9– OP400 MULTIPLE OUTPUT TRACKING VOLTAGE REFERENCE Figure 7 shows a circuit that provides outputs of 10 V, 7.5 V, 5 V, and 2.5 V for use as a system voltage reference. Maximum output current from each reference is 5 mA with load regulation under 25 mV/mA. Line regulation is better than 15 mV/V and output voltage drift is under 20 mV/∞C. Output voltage noise from 0.1 Hz to 10 Hz is typically 75 mV p-p from the 10 V output and proportionately less from the 7.5 V, 5 V, and 2.5 V outputs. Figure 7.
