Description

The PGA204BU is one member of the PGA204 series.The PGA204 is low cost, general purpose programmable-gain instrumentation amplifier  offering excellent accuracy. Gains are digitally selected: PGA204-1, 10, 100, 1000. The precision and versatility, and low cost of the PGA204 make it ideal for a wide range of applications.

Features of the PGA204 are:(1)low offset voltage: 50V max;(2)low input bias current: 2nA max;(3)low quiescent current: 5.2mA typ;(4)16-pin plastic dip, SOL-16 packages.This integrated circuit can be damaged by ESD. Burr-Brown recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.The output offset adjustment can be used to trim sensor or system offsets without affecting drift. The voltage applied to the Ref terminal is summed with the output signal. Low impedance must be maintained at this node to assure good common-mode rejection. This is achieved by buffering the trim voltage with an op amp as shown.

The absolute maximum ratings of the PGA204 can be summarized as:(1)supply voltage:±18V;(2)analog input voltage range:±40V;(3)logic input voltage range:±Vs;(4)output short-circuit (to ground): continuous;(5)operating temperature:40°C to +125°C;(6)storage temperature:40°C to +125°C;(7)junction temperature:+150°C;(8)lead temperature (soldering 10s):+300°C.This device has been designed and tested for the specified operating ranges. Proper operation outside of these levels is not guaranteed. Exposure to absolute maximum ratings may cause permanent damage.Parameters are not 100% tested.Specifications are based on initial characterization and are tested after any design process modification that might affect operational frequency.Feedback also can be taken from the register, regardless of whether the output function is to be combinatorial or registered. When implementing a combinatorial output function, registered feedback allows for the internal latching of states without giving up the use of the external output.
