AD9236

• Product Introduction

AD9236 12-Bit, 80 MSPS, 3 V Analog-to-Digital Converter (ADC)

The AD9236 is a single-chip, 12-bit, 80 MSPS analog-to-digital converter (ADC) that operates from a single 3 V supply and has a built-in high-performance sample-and-hold amplifier (SHA) and voltage reference. It features a multi-stage differential pipeline architecture with built-in output error correction logic that provides 12-bit accuracy at 80 MSPS data rates and ensures no code loss over the entire operating temperature range.

With a wide-bandwidth, true differential sampling hold amplifier (SHA), users can select a variety of input ranges and offsets, including single-ended applications. The device is suitable for multiplexing systems that switch full-scale levels in a continuous channel, as well as for sampling single-channel inputs at frequencies well above the Nyquist rate. The AD9236 consumes reduced power compared to previous analog-to-digital converters and is suitable for applications such as communications, imaging, and medical ultrasound.

A single-ended clock input is used to control all internal conversion cycles. A duty cycle stabilizer (DCS) is used to compensate for large clock duty cycle fluctuations while maintaining excellent performance. The digital output data format is standard binary or binary complement. The over-range (OTR) signal indicates an overflow condition, which can be determined by the highest significant bit whether it is an overflow or an overflow.

The AD9236 is manufactured using an advanced CMOS process and is available in 28-pin TSSOP and 32-pin LFCSP packages and is rated for an industrial temperature range of -40°C to +85°C.
