DC characteristics of the HA-5101 assure accurate performance. The 0.5mV offset voltage is externally adjustable and offset voltage drift is just 3µV/oC. An offset current of only 30nA reduces input current errors and an open loop voltage gain of 1 x 106V/V increases loop gain for low distortion amplification. The HA-5101 is ideal for audio applications, especially lowlevel signal amplifiers such as microphone, tape head and phono cartridge preamplifiers. Additionally, it is well suited for low distortion oscillators, low noise function generators and high Q filters.

Input Protection Offset Adjustment The HA-5101 has built-in back-to-back protection diodes which will limit the differential input voltage to approximately 5 HA-5101 7V. If the 5101 will be used in conditions where that voltage may be exceeded, then current limiting resistors must be used. No more than 25mA should be allowed to flow in the HA-5101’s input. If saturation cannot be avoided the HA-5101 recovers from a 25% overdrive in about 6.5µs (see photos).

Output is overdriven negative and recovers in 6µs. Output Saturation When an op amp is overdriven, output devices can saturate and sometimes take a long time to recover. Saturation can be avoided (sometimes) by using circuits such as: V+ R1 R2 + R3 VSOURCE R4 V- Typical Performance Curves 8 INPUT NOISE VOLTAGE (nV/√Hz) INPUT NOISE CURRENT (pA/√Hz) 7 6 5 4 3 2 1 0 10 100 1K FREQUENCY (Hz) 10K 100K CURRENT VOLTAGE 1500 OFFSET VOLTAGE (µV) 1000 500 0 -50 -25 0 25 50 75 100 125 TEMPERATURE (oC) FIGURE 6.
