GENERAL DESCRIPTION  
The OP400 is the first monolithic quad operational amplifier  
that features OP77-type performance. Precision performance is  
not sacrificed with the OP400 to obtain the space and cost  
savings offered by quad amplifiers.  
The OP400 features low power consumption, drawing less than  
725 µA 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, half that of most competitive devices.  
The OP400 features an extremely low input offset voltage of less  
than 150 µV with a drift of less than 1.2 µV/°C, guaranteed over  
the full military temperature range. Open-loop gain of the  
OP400 is more than 5 million into a 10 kΩ load, input bias  
current is less than 3 nA, CMR is more than 120 dB, and PSRR  
is less than 1.8 µV/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 is an ideal choice for applications requiring multiple  
precision operational amplifiers and where low power  
consumption is critical.

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

OP400A  
A dual instrumentation amplifier that consumes less than  
33 mW of power per channel is shown in Figure 31. 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.

DIFFERENTIAL OUTPUT INSTRUMENTATION  
AMPLIFIER  
BIPOLAR CURRENT TRANSMITTER  
In the circuit of Figure 32, 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 MΩ, and linearity is better than 16 bits  
with gain set for a full-scale input of 100 µV.  
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 instrumenta-  
tion amplifier shown in Figure 33 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 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. The PSRR of the amplifier is less than 1 µV/V with  
CMRR (G = 1000) better than 115 dB. Offset voltage drift is  
typically 0.4 µV/°C over the military temperature range.

and output voltage drift is under 20 µV/°C. Output voltage  
noise from 0.1 Hz to 10 Hz is typically 75 µV p-p from the  
10 V output and proportionately less from the 7.5 V, 5 V, and  
2.5 V outputs.  
Figure 34 shows a circuit that provides outputs of 10 V, 7.5 V, 5 V,
