Alfa Rpar - KP1100CK2 - Monolithic Sample-and-Hold Circuits
Product information "Alfa Rpar - KP1100CK2 - Monolithic Sample-and-Hold Circuits"
The 1100CК2, К1100СК2, КР1100СК2 are monolithic sample-and-hold (SHA) circuits, controlled by signal LOGIC, stores the instantaneous values of the input signal and for a certain time maintain a constant DC voltage at the output with a high accuracy.
The wide bandwidth allows the 1100CК2 to be included inside the feedback loop of 1 MHz op amps without having stability problems. Input impedance of 10^10 Ω allows high source impedances to be used without degrading accuracy.
The overall design ensures no feedthrough from input to output in the hold mode, even for input signals equal to the supply voltages. Logic inputs on the 1100К2 are fully differential with low input current, allowing for direct connection to TTL, PMOS, and CMOS. Differential threshold is 1.4 V. The 1100CК2 will operate from ±5V to ±15V supplies.
The 1100CК2 OUTPUT tracks the INPUT signal by charging and discharging the hold capacitor (CH). The OUTPUT can be held at any given time by pulling the LOGIC input low relative to the LOGIC REFERENCE voltage and resume sampling when LOGIC returns high. Additionally, the OFFSET pin can be used to zero the offset voltage present at the INPUT.
The 1100CK2 and K(KP)1100CK2 devices have a sample mode and hold mode controlled by the LOGIC voltage relative to the LOGIC REFERENCE voltage. The device is in sample mode when the LOGIC input is pulled high relative to the LOGIC REFERENCE voltage and in hold mode when the LOGIC input is pulled low relative to the LOGIC REFERENCE. In sample mode, the output is tracking the input signal by charging and discharging the hold capacitor. Smaller values of hold capacitance will allow the output to track faster signals. In hold mode the input signal is disconnected from the signal path and the output retains the value on the hold capacitor.
The nominal value of the supply voltage UСС1,2=±15V for 1100СК2B и UСС1,2=±12V for 1100СК2А, К1100СК2, КР1100СК2.
1100CK2, К1100СК2 are released in TO5-8, KP1100CK2 in PDIP-8(300Mil).

Safety Instructions for Electronic and Mechanical Components
Intended Use:
• Electronic components, including potentiometers, knobs, switches, connectors, resistors, capacitors or integrated circuits (ICs), are designed for use in electronic circuits and devices.
• Use these components only for their intended purposes in electrical and electronic applications, according to their specified voltage, current, and environmental conditions.
• Any use outside the intended applications may result in malfunction or safety risks.
Handling and Installation
Installation:
• Handle electronic components with appropriate tools, such as tweezers, to avoid physical damage or exposure to electric shock.
• Ensure that the components are installed in the correct orientation and according to manufacturer specifications to avoid malfunction or damage to the circuit.
Storage:
• Store components in a dry, cool, and static-free environment to avoid damage from moisture, extreme temperatures, or electrostatic discharge (ESD).
• Avoid direct exposure to sunlight, which could affect component stability and performance.
Protection from Static Electricity:
• Use antistatic equipment (e.g., wrist straps, ESD mats) when handling electronic components to prevent electrostatic discharge, which can damage sensitive devices like ICs.
Compatibility:
• Make sure electronic components are compatible with the circuit in terms of voltage, current, and other technical specifications.
Warnings
Electrical Shock Hazard:
• Some components can retain charge even when disconnected. Use appropriate tools and take precautions when handling components to minimize the risk of electric shock.
Burn or Fire Risk:
• Overloading or misusing electronic components may result in overheating, which could lead to burning or fires. Ensure that components are used within their specified voltage and current ratings.
Danger from Misuse:
• Incorrect handling or use outside specified limits can damage the components or affect the performance and functionality of connected devices. Only use components within their specified tolerances and conditions.
Choking Hazard:
• Small electronic components can pose a choking hazard if swallowed. Keep components out of reach of children.
