HTCSEMI HT8620
The HT8620 is a low cost, high accuracy instrumentation amplifier that requires only one external resistor to set gains of and DIP packaging that is smaller than discrete designs and offers lower power (only 1.3 mA max supply current), making The HT8620, with its high accuracy of 40 ppm maximum nonlinearity, low offset voltage of 50 µV max, and offset drift of 0.6 µV/°C max, is ideal for use in precision data acquisition systems, such as weigh scales and transducer interfaces. The low input bias current of 1.0 nA max is made possible with the use of Superϐeta processing in the input stage. The HT8620 works well as a preamplifier due to its low input voltage noise of 9 nV/√Hz at 1 kHz, 0.28 µV p-p in the 0.1 Hz to 10 Hz band, and 0.1 pA/√Hz input current noise.
