GENERAL DESCRIPTION  
The OP200 is the first monolithic dual operational amplifier  
to offer OP77 type precision performance. Available in the  
industry standard 8-lead pinout, the OP200 combines precision  
performance with the space and cost savings offered by a dual  
amplifier.  
Power consumption of the OP200 is low, with each amplifier  
drawing less than 725 µA of supply current. The total current  
drawn by the dual OP200 is less than one-half that of a single  
OP07, yet the OP200 offers significant improvements over this  
industry-standard op amp. The voltage noise density of the  
OP200, 11 nV/√Hz at 1 kHz, is half that of most competitive  
devices.  
The OP200 features an extremely low input offset voltage of  
less than 75 µV with a drift below 0.5 µV/°C, guaranteed over  
the full military temperature range. Open-loop gain of the OP200  
exceeds 5,000,000 into a 10 kΩ load; input bias current is under  
2 nA; CMRR is over 120 dB; and PSRR is below 1.8 µV/V. On-chip  
Zener zap trimming is used to achieve the extremely low input  
offset voltage of the OP200 and eliminates the need for offset  
pulling.  
The OP200 is pin compatible with the OP221, LM158,  
MC1458/MC1558, and LT1013.  
The OP200 is an ideal choice for applications requiring multiple  
precision op amps and where low power consumption is critical.  
For a quad precision op amp, see the OP400.

OP200  
Data Sheet  
APPLICATIONS INFORMATION  
The OP200 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 OP200.  
PRECISION ABSOLUTE VALUE AMPLIFIER  
The circuit in Figure 31 is a precision absolute value amplifier  
with an input impedance of 10 MΩ. The high gain and low TCVOS  
of the OP200 ensure accurate operation with microvolt input  
signals. In this circuit, the input always appears as a common-  
mode signal to the op amps. The CMRR of the OP200 exceeds  
120 dB, yielding an error of less than 2 ppm.  
DUAL LOW POWER INSTRUMENTATION  
AMPLIFIER  
+15V  
A dual instrumentation amplifier that consumes less than 33 mW  
of power per channel is shown in Figure 30. 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 (gain = 1000). Offset voltage drift is typically 0.2 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 7.

PRECISION CURRENT PUMP  
The maximum output current of the precision current pump

DUAL 12-BIT VOLTAGE OUTPUT DAC  
DUAL PRECISION VOLTAGE REFERENCE  
The dual output DAC shown in Figure 33 is capable of providing  
untrimmed 12-bit accurate operation over the entire military  
temperature range. Offset voltage, bias current, and gain errors  
of the OP200 contribute less than 1/10 of an LSB error at 12 bits  
over the military temperature range.  
A dual OP200 and a REF43, a 2.5 V reference, can be used to  
build a 2.5 V precision voltage reference. Maximum output  
current from each reference is 10 mA with load regulation  
under 25 μV/mA. Line regulation is better than 15 μV/V 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. R1 and D1 ensure  
correct startup.
