MAX492/MAX494/MAX495
Single/Dual/Quad, Micropower,
Single-Supply Rail-to-Rail Op Amps
the op amp in an inverting configuration (Figure 3a);
connect resistor R3 between the noninverting input and
the input signal when using the op amp in a noninvert-
ing configuration (Figure 3b). Select R3 to equal the
parallel combination of R1 and R2. High source resis-
tances will degrade noise performance, due to the ther-
mal noise of the resistor and the input current noise
(which is multiplied by the source resistance).
Input Stage Protection Circuitry
The MAX492/MAX494/MAX495 include internal protec-
tion circuitry that prevents damage to the precision
input stage from large differential input voltages. This
protection circuitry consists of back-to-back diodes
between IN+ and IN- with two 1.7k
resistors in series
(Figure 4). The diodes limit the differential voltage
applied to the amplifiers’ internal circuitry to no more
than VF, where VF is the diodes’ forward-voltage drop
(about 0.7V at +25°C).
Input bias current for the ICs (±25nA typical) is speci-
fied for the small differential input voltages. For large
differential input voltages (exceeding VF), this protec-
tion circuitry increases the input current at IN+ and IN-:
(VIN+ - VIN- ) - VF
Input Current = ———————————
2 x 1.7k
For comparator applications requiring large differential
voltages (greater than VF), you can limit the input cur-
rent that flows through the diodes with external resistors
