CA3080E Description
The CA3080 is Gatable-Gain Blocks that utilize the distinctive 2MHz operational -transconductance amplifier (OTA) idea represented in Application note AN6668, “ Applications of the CA3080 and CA3080A High Performance Operational Transconductance Amplifiers “. It has a differential input , a single-ended, push-pull as well as class A output. Additionally, these varieties have associate electronic amplifier bias input which can be used either for gating or for linear gain control. These varieties even have a high output impedance and their transconductance (gM) is directly proportional to the amplifier bias current (IABC).The CA3080 are notable for their glorious slew rate (50V/μs),which makes them especially needful for multiplexer and fast unity-gain voltage followers.
Features
· Slew rate ( Unity gain , compensated ) : 50V/μs
· Adjustable Power Consumption : 10μW to 30μW
· Flexible Supply Voltage Range : ±2V to ±15V
· Fully Adjustable Gain : 0 to gMRL Limit
· Tight gM Spread : 2:1
· Extended gM Linearity : 3 Decades
PINOUTS
CA3080E has 2 as an input pin and 6 as an output pins, the non-inverting and inverting input pins are protected from overload using protection circuitry. The CA3080E is obtainable in a package of 8 Ld PDIP.
Pin Number | Pin Name | Description |
1,8 | NC | Not connected, keep it open |
2 | Inverting Input | Inverting input signal |
3 | Non-inverting Input | Non-inverting input signal |
4 | V- | Ground or Negative power supply voltage pin |
5 | Amplifier bias input | Small amount of current that flows in or out of the inputs (ideally it is Zero) |
6 | OUTPUT | Output pin |
7 | V+ | Positive DC voltage supply pin |
Applications
· Sample and Hold: The CA3080E is employed in sample and hold circuit. The sample and hold circuit is an electronic circuit which creates the samples of the voltage given to it as an input , and then , it holds these samples for the definite time. The time throughout which sample and hold circuit generates the sample of the input signal is termed as Sampling time.
· Multiplier: A multiplier is a combinational logic circuit that can be utilize for multiplying binary digits.
· Multiplexer: The availability of the bias current terminal, IABC , permits the device to be gated for its applications. Below figure shows a simple two-channel multiplexer system using two CA3080 OTA devices. The most level-shift from input to output is low (Which is approximately 5mV for the CA3080). This shift is set by the amplifier input offset voltage of the particular device used, as a result of the open-loop gain of the system is usually 100dB while the loading on the output of CA3080A is low. To additional increase the gain and minimize the effects of loading, an extra buffer and/or gain-stage may be added.
· Comparator: A comparator circuit compares two voltages and outputs either a one or a zero to mention which is larger. Comparators are sometimes used to check whether an input has reached some predetermined value or not.
· Voltage Follower: Voltage follower is employed to provide high impedance (of several M?) at input so less current is drawn from the circuit. The voltage across load equals to input voltage as gain is unity. With no voltage follower the voltage at load is going to be very less compared to input voltage.
