AD9266-65EBZ

• Product introduction

AD9266-65EBZ Monolithic, Single, 16-Bit, 20/40/65/80 MSPS Analog-to-Digital Converter (ADC)

The AD9266 is a monolithic, single, 16-bit, 20/40/65/80 MSPSAnalog-to-digital converters(ADC) from a 1.8 V supply with high performance track-and-hold circuitry and on-chip reference.

It features a multistage differential pipelined architecture with built-in output error correction logic, 16-bit accuracy at 80 MSPS data rates, and guaranteed no missing codes over the entire operating temperature range.

The ADC includes features that provide optimal flexibility and minimal system cost, such as programmable clock and data alignment, and generation of programmable digital test patterns. Available digital test codes include built-in fixed and pseudo-random codes, as well as user-defined test codes input via the serial port interface (SPI).

A differential clock input is used to control all internal conversion cycles. An optional duty cycle stabilizer (DCS) is used to compensate for large clock duty cycle fluctuations while maintaining excellent overall ADC performance.

The interleaved digital output data format is offset binary, gray code, or twos complement. A data output clock (DCO) is used to ensure that the receive logic has the correct latch timing. Supports 1.8 V and 3.3 V CMOS levels.

The AD9266 is available in a 32-lead lead-free LFCSP package and is specified over the industrial temperature range of −40°C to +85°C.

Product Focus

1. The AD9266 operates from a single 1.8 V analog supply, while the digital output driver operates from a separate supply to accommodate 1.8 V to 3.3 V logic.
2. The patented sample-and-hold circuit maintains excellent performance at input frequencies up to 200 MHz at low cost, low power consumption, and ease of use.
3. The standard serial port interface supports a variety of product features and functions such as data output formatting, internal clock divider, power-down mode, DCO and data output (D15_D14 to D1_D0) timing and offset adjustment, and reference mode.
4. The AD9266 is available in a 32-lead LFCSP package and is RoHS compliant, pin-compatible with the AD9609, 12-bit ADC, AD9629, and AD9649, a 14-bit ADC, so 10- and 16-bit converters with sample rates from 20 MSPS to 80 MSPS can be easily upgraded.
