AD7655ASTZ

AD7655 is a low cost, simultaneous sampling, 16bit, charge redistribution SAR, analogue-to-digital converter that operates from a single 5V power supply. It contains two low noise, wide bandwidth, track-and-hold amplifiers that allow simultaneous sampling, a high speed 16bit sampling ADC, an internal conversion clock, error correction circuits, and both serial and parallel system interface ports. Each track-and-hold has a multiplexer in front to provide a 4-channel input ADC. Typical application includes AC motor control, 3-phase power control, 4-channel data acquisition, uninterrupted power supplies and communications.

• 4-channel, 16bit resolution ADC and 2 track-and-hold amplifiers

• Analog input voltage range: 0V to 5V
• No pipeline delay
• Parallel and serial 5V/3V interface
• SPI®/QSPI™/MICROWIRE™/DSP compatible
• Single 5V supply operation
• Power dissipation: 120mW typical and 2.6mW at 10KSPS
• Pin-to-pin compatible with the AD7654
• 48 lead LQFP package, operating temperature range from -40°C to +85°C
