4 Channels 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)
OPA1644AIPW Overview
The linear amplifier is packaged in a 14-TSSOP (0.173, 4.40mm Width) case. This is a Audio type op amp. Linear amplifier is delivered in a Tube case. The number of terminations approaches 14. Buffer amplifier has a total of 14 pins. Please take in mind that this instrumentation amplifier should be run at 18V. The buffer op amp includes 14 pins. Regarding input offset voltage, op amp rates 3.5mV. Surface Mount is the recommended mounting type for this linear amplifier. With regard to operating temperature, this op amp functions well at -40°C~85°C. This op amp can operate from a supply current at 1.8mA. Voltage gain should remain at 134dB. The op amp ic has 4 channels on it. This op amp ic outputs Rail-to-Rail signals, which is one of the many benefits it has. SoundPlus™ corresponds to the op amp's series.
