However, strong static fields should be avoided, as it is possible for the strong fields to cause degraded diode junction characteristics, which may result in increased input leakage currents. Latchup Avoidance Junction-isolated CMOS circuits employ configurations which produce a parasitic 4-layer (PNPN) structure. The 4 4-layer structure has characteristics similar to an SCR, and under certain circumstances may be triggered into a low impedance state resulting in excessive supply current. To avoid this condition, no voltage greater than 0.3V beyond the supply rails may be applied to any pin. In general, the op amp supplies must be established simultaneously with, or before any input signals are applied. If this is not possible, the drive circuits must limit input current flow to 2mA to prevent latchup. ICL7621, ICL7641, ICL7642 Choosing the Proper IQ Each device in the ICL76XX family has a similar IQ setup scheme, which allows the amplifier to be set to nominal quiescent currents of 10µA, 100µA or 1mA. These current settings change only very slightly over the entire supply voltage range. The ICL7611/12 have an external IQ control terminal, permitting user selection of each amplifiers’ quiescent current. The ICL7621 and ICL7641/7642 have fixed IQ settings: Typical Operating Characteristics). During the transition from Class A to Class B operation, the output transfer characteristic is nonlinear and the voltage gain decreases. Frequency Compensation The ICL76XX are internally compensated, and are stable for closed loop gains as low as unity with capacitive loads up to 100pF. Operation At VSUPPLY = ±1V Operation at VSUPPLY = ±1V is guaranteed for the ICL7642C only. ICL7621 (Dual) - IQ = 100µA ICL7641 (Quad) - IQ = 1mA ICL7642 (Quad) - IQ = 10µA NOTE: The output current available is a function of the quiescent current setting. For maximum peak-to-peak output voltage swings into low impedance loads, IQ of 1mA should be selected. Output Stage and Load Driving Considerations Each amplifiers’ quiescent current flows primarily in the output stage. This is approximately 70% of the IQ settings. This allows output swings to almost the supply rails for output loads of 1MΩ, 100kΩ, and 10kΩ, using the output stage in a highly linear class A mode. In this mode, crossover distortion is avoided and the voltage gain is maximized. However, the output stage can also be operated in Class AB for higher output currents. (See graphs under Output swings to within a few millivolts of the supply rails are achievable for RL ≥ 1MΩ. Guaranteed input CMVR is ±0.6V minimum and typically +0.9V to -0.7V at VSUPPLY = ±1V. For applications where greater common mode range is desirable, refer to the ICL7612 data sheet. Typical Applications The user is cautioned that, due to extremely high input impedances, care must be exercised in layout, construction, board cleanliness, and supply filtering to avoid hum and noise pickup. Note that in no case is IQ shown. The value of IQ must be chosen by the designer with regard to frequency response and power dissipation. +5 VIN +5 ICL76XX + VOUT VIN - ICL76XX - VOUT RL ≥ 10kΩ TO CMOS OR LPTTL LOGIC + 100kΩ 1MΩ FIGURE 1.
