36mA per Channel 2pA 120 dB Instrumentational OP Amps 0.00002μA 4.5V~36V ±2.25V~18V OPA1644 14 Pins 14-TSSOP (0.173, 4.40mm Width)
OPA1644AIPWR Overview
There is a 14-TSSOP (0.173, 4.40mm Width) case package that contains the instrumentation amplifiers. The instrumentation amplifier in this picture is of the Audio-type. Upon delivery, op amp ic is packaged in a Tape & Reel (TR) case. We are approaching the 14h termination of the year. In total, there are 14 pins on this op amp ic. This linear amplifier should be powered by an 18V battery. 14 pins are located on the operational amplifiers. The input offset voltage is 3.5mV. This electrical part should be mounted using type Surface Mount. In terms of operating temperatures, this buffer amplifier works very well at a temperature of around -40°C~85°C . The buffer amplifier is capable of operating from a supply current of 1.8mA . It is recommended to keep the voltage gain at 134dB at all times. One of the many benefits of this op amp ic is that it emits Rail-to-Rail signals. The total number of elements in this buffer amplifier is 4. This linear amplifier pack is based on the TR axis. Instrumentation amplifiers are numbered by their SoundPlus™ series.
