AD9258BCPZRL7-125

Analog To Digital Converters (ADC) Overview

The AD9258BCPZRL7-125 is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 125 MSPS. It features a multistage differential pipelined architecture with integrated output error correction logic. The device supports flexible analog input ranges from 1 V p-p to 2 V p-p and offers configurable digital outputs in either 1.8 V CMOS or LVDS formats. Key performance metrics include a signal-to-noise ratio (SNR) of 77.6 dBFS and a spurious-free dynamic range (SFDR) of 88 dBc at 70 MHz input frequency and 125 MSPS sampling rate. Power consumption is specified at 750 mW under typical operating conditions.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix RL7 indicates reel packaging when sourcing components. Confirm that the -125 designation corresponds to the 125 MSPS speed grade. Ensure compatibility with the required 1.8 V supply voltages for both analog and digital domains. Check for RoHS compliance status if environmental regulations apply to the target assembly process.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring high linearity and low power consumption in a compact form factor. Consider the pin compatibility with the AD9268 if future migration to 16-bit resolution is anticipated. Evaluate the need for on-chip dithering to improve SFDR performance with low-power analog inputs. Ensure the system clock can support the integer 1-to-8 divider for IF sampling frequencies up to 300 MHz.

Analog To Digital Converters (ADC) Part Context

The AD9258 belongs to Analog Devices' family of high-performance dual ADCs designed for communications applications. It shares pin compatibility with the AD9268, AD9251, AD9231, and AD9204, facilitating design flexibility across different resolution and speed requirements within the same product line.

Analog To Digital Converters (ADC) Replacement Considerations

The AD9268 serves as a direct pin-compatible upgrade path for designs requiring 16-bit resolution. For lower sample rate and power applications, consider the AD9251, AD9231, or AD9204 series which share the same footprint.
