The AD7452BRTZ-R2 is a 12-bit high speed, low power, successive approximation (SAR) Analog-to-digital Converter (ADC) that features a fully differential analog input. This part operates from a single 3/5V power supply and features throughput rates up to 555kSPS. The part contains a low noise, wide bandwidth, differential track-and-hold amplifier (T/H) that can handle input frequencies up to 3.5MHz. The value of the reference voltage determines the common-mode voltage range of the part. With this truly differential input structure and variable reference input, the user can select a variety of input ranges and bias points. The conversion process and data acquisition are controlled using CS and the serial clock, allowing the device to interface with microprocessors or DSPs. The input signals are sampled on the falling edge of CS and the conversion is also initiated at this point. The SAR architecture of this part ensures that there are no pipeline delays.
● Low power at max throughput rate
● Fully differential analog input
● Flexible power/serial clock speed management
● No pipeline delays
● High speed serial interface SPI™/QSPI™/MICROWIRE™/DSP compatible
