Bias current is specified under warmed-up and operating conditions, as opposed to a junction temperature of +25°C. Laser-trimmed thin-film resistors offer improved offset voltage and noise performance. The OPA606 is internally compensated for unity-gain stability. 1 Trim 5 Trim 7 +VCC 2 –In 3 +In 6 VOUT Simplified Circuit 4 –VCC Difet®; Burr-Brown Corp. BIFET®; National Semiconductor Corp.

As with most amplifiers, externally trimming the remaining offset can change drift performance by about 0.5µV/°C for each millivolt of adjusted offset. Note that the trim (Figure 1) is similar to operational amplifiers such as LF156 and OP-16. The OPA606 can replace most other amplifiers by leaving the external null circuit unconnected. +VCC (1) 7 2 3 100kΩ 1 5 OPA606 4 6 NOTE: (1) 10kΩ to 1MΩ Trim Potentiometer (100kΩ Recommended) ±50mV Typical Trim Range –VCC FIGURE 1. Offset Voltage Trim. ® 7 OPA606 INPUT PROTECTION Static damage can cause subtle changes in amplifier input characteristics without necessarily destroying the device. In precision operational amplifiers (both bipolar and FET types), this may cause a noticeable degradation of offset voltage and drift. Static protection is recommended when handling any precision IC operational amplifier. If the input voltage exceeds the amplifier’s negative supply voltage, input current limiting must be used to prevent damage. CIRCUIT LAYOUT Wideband amplifiers require good circuit layout techniques and adequate power supply bypassing. Short, direct connections and good high frequency bypass capacitors (ceramic or tantalum) will help avoid noise pickup or oscillation. GUARDING AND SHIELDING As in any situation where high impedances are involved, careful shielding is required to reduce “hum” pickup in input leads. If large feedback resistors are used, they should also be shielded along with the external input circuitry. Leakage currents across printed circuit boards can easily exceed the bias current of the OPA606. To avoid leakage problems, it is recommended that the signal input lead of the OPA606 be wired to a Teflon® standoff. If the OPA606 is to be soldered directly into a printed circuit board, utmost care must be used in planning the board layout. A “guard” pattern should completely surround the high impedance input leads and should be connected to a low impedance point which is at the signal input potential (see Figure 3). 0.1% 2kΩ 0.1% 2 2kΩ 0.1% 5kΩ –15V 3 DUT 4 7 6 100pF 3k Ω 2N4416 Noninverting Buffer 2 OPA606 In 3 6 Out In Inverting In 2 OPA606 3 6 Out 2 OPA606 3 6 Out TO-99 Bottom View 45 3 2 1 6 7 8 Mini-DIP Bottom View BOARD LAYOUT FOR INPUT GUARDING Guard top and bottom of board.
