AD7476/AD7477/AD7478 are 1 MSPS, 12-/10-/8-Bit ADCs in a 6-Lead SOT-23 package. They feature fast throughput rate, low power consumption, wide input bandwidth, and flexible power/serial clock speed management. They are suitable for applications such as battery-powered systems, personal digital assistants, medical instruments, mobile communications, instrumentation and control systems, data acquisition systems, high-speed modems, and optical sensors.
The document describes the AD7476/AD7477/AD7478 family of analog-to-digital converters (ADCs). These devices are 12-bit, 10-bit, and 8-bit successive-approximation ADCs respectively, featuring a throughput rate up to 1 MSPS. They operate from a single power supply ranging from 2.35 V to 5.25 V and include a low noise track-and-hold amplifier with an input bandwidth in excess of 6 MHz.
The datasheet provides comprehensive electrical specifications for dynamic performance, DC accuracy, analog inputs, logic levels, conversion rates, and power requirements. It distinguishes between A, B, and S versions based on temperature ranges and specific operating conditions, covering parameters such as Signal-to-Noise Ratio (SNR), Total Harmonic Distortion (THD), Integral Nonlinearity (INL), and quiescent current.
