ADM660ARZ-REEL7

The ADM660ARZ-REEL7 is a CMOS switched-capacitor voltage converter, specifically a charge pump, designed and manufactured by Analog Devices. This device is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) package and is intended for use in DC-to-DC power conversion applications.

Key Features:

• Charge Pump Converter: The ADM660ARZ-REEL7 operates as a charge pump converter, capable of inverting or doubling the input voltage. For input voltages ranging from +1.5V to +7V, the output voltage can be inverted to -1.5V to -7V, or doubled to 5V to 14V (in the case of inversion, VOUT = -VIN; in the case of doubling, VOUT = 2 x VIN, but note that doubling is only applicable for ADM660, as mentioned in some sources).
• Output Current: The device can provide an output current of up to 100mA.
• Frequency Control: The ADM660ARZ-REEL7 allows for frequency control, with selectable charge pump operating frequencies of either 25kHz or 120kHz. This feature enables optimization of capacitor size and static current based on the application requirements.
• Low Power Consumption: With a typical static current of 600μA, this charge pump converter is suitable for low-power applications.
• Operating Temperature Range: The device can operate within a temperature range of -40°C to +85°C.
• Pin Compatibility: The ADM660ARZ-REEL7 is pin-compatible with certain other devices, such as the MAX660, MAX665, and ICL7660, providing flexibility in design and upgrade paths.

Applications:

The ADM660ARZ-REEL7 is ideal for a variety of applications where DC-to-DC power conversion is required, including:

• Handheld instruments
• Portable computers
• Remote data acquisition systems
• Any system requiring a negative supply rail in a single-supply environment

In summary, the ADM660ARZ-REEL7 is a versatile and reliable charge pump voltage converter that offers efficient DC-to-DC power conversion with low power consumption and a wide operating temperature range. Its pin compatibility with other devices and selectable charge pump frequencies make it a suitable choice for a range of applications.
