Overview
The MAX114CAG+T is a microprocessor-compatible, 8-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is part of the MAX114/MAX118 series, which includes 4-channel and 8-channel ADCs. The MAX114CAG+T specifically is a 4-channel ADC that operates from a single +5V supply and utilizes a half-flash technique to achieve a conversion time of 660ns, resulting in a sampling rate of 1 Msps (mega-samples per second).

Key Features
- Microprocessor-compatible design, allowing the ADC to appear as a memory location or I/O port without external interface logic.
- Low power consumption with a power-down mode that reduces current to typically 1µA, and quick recovery time of less than 200ns from power-down mode.
- Includes a track/hold circuit to digitize fast analog signals.
- Data outputs use latched, three-state buffer circuitry for direct connection to an 8-bit parallel microprocessor data bus or system input port.
- Ratiometric operation is supported through the input/reference configuration.
Applications
The MAX114CAG+T is suitable for various applications requiring high-speed, low-power analog-to-digital conversion. These include:
- Burst Mode applications where the ADC wakes up from a low-power state at specified intervals to sample analog input signals.
- Systems requiring microprocessor-compatible ADCs with minimal external interface logic.
- Applications needing fast conversion times and low power consumption, such as in data acquisition systems, industrial control, and medical devices.
