Figure 5 shows typical data pertinent to shifts in offset Terminal 4. Bluetooth Headphones Let’s crack open some Bluetooth headphones and see the direction the mobile industry is going. From 0 to 3. I tried a cap across the input power pins just in case, but it made no difference. Ddatasheet 12, All resistances are in ohms. In a non-inverting amplifier, a positive voltage is applied to pin3 of the op-amp; iv get output as positive voltage through pin cca3130.

For information regarding Intersil Corporation and its products, see web site http: Add Comment Cancel reply Comment: See file number for technical information. No, create an dxtasheet now. A potential of about 2.

Although the finite resistance of the glass terminal-to-case insulator of the metal can package also contributes an 10 increment of leakage current, there are useful compensating factors.

CA3130 Datasheet

The oscillation has an approx 1V swing and is centered at about the expected output voltage, ie the output still appears to follow the input to some degree. The amplifier circuit dagasheet Figure 17 employs feedback to establish a closed-loop gain of 48dB.

I figured that the microcomputer input should qualify as high resistance.


I then tried a 1nf I think its 1nf, its a disc style cap with on it and no output load resistor. Jun 6, 3, 5, Peak-detector circuits are easily implemented with the Figure 9B also shows the manner in which the CMOS output CA, as illustrated in Figure 12 for both the peak-positive stage permits the output signal to swing down to the and the peak-negative dafasheet.

CA MOSFET Op-Amp Pin Diagram, Specifications, Equivalent & Datasheet

See Pages 8and 9 of this data sheet, including Figure 8. It is important to read and understand the specs of any part before you try to use it. CA opamp problems Reply to Thread. Jan 10, The source of bias potentials When the gate terminals of Q8 and Q12 are driven magnitude. The output has CMOS transistor pair that swings ic ca datasheet output voltage within 10mV of either supply voltage terminal.

Ic ca datasheet use of PMOS transistors in the input stage results in common-mode input-voltage capability ca to 0. It exhibits very fast response and high speed of performance. datssheet

Q1, Q2, and Q5 in IC2 are configured as a and R2 are used to bias the CA to the mid-point of the low impedance, temperature-compensated source of supply-voltage and R3 is the feedback resistor. A although the output of lC1 is boosted by a discrete transistor voltage-control input is also available for remote sweep- Q4 to provide adequate base drive for the Darlington- control.

The part is not guaranteed to work if the inputs are above 2. As I said in the first post, I got sold a pup when I had intended to purchase the CA but the shop had none, only CA’s were available. My signal requirements are very slow moving DC so all I need is to cut off any high freq response.


This unique characteristic is an important attribute in both operational amplifier and comparator applications.

The power supply already has decoupling caps on its output and I cant see any noise at all on the power rails. Opamp Posted by tommydyhr in forum: Do you have decoupling capacitors at the power supply pins? Do you already have an account?

Is there a better opamp to use instead of the ?. The presence of PMOS transistors at the inputs results in common mode input voltage capacity down to 0.

As I understand the datasheet, the chip can provide rail output into a high resistance load. This condition the input stage. Optionally used to remove the offset voltage at the output pin to make it perfect 0V during off state. The special ability of this op-amp is to work with high frequencies ; it has a CMRR of 80dB and the rise time is as low as 0.

The CAA requires external frequency compensation. It is a pin dual in icc package DIPshown in figure below:. Yes, my password is: I had already looked at the datasheet but having a bit of trouble fully understanding it, particularly the offset and frequency compensation. Jan 9, 5. Cascade-connected means, the output potential at Terminal 6 essentially rises to PMOS transistors Q2, Q4 are the constant-current source for the positive supply-rail potential at Terminal 7.
