AD9204BCPZRL7-20

Overview

The AD9204BCPZRL7-20 is a monolithic, dual-channel, 1.8 V supply, 10-bit analog-to-digital converter (ADC) operating at a maximum sample rate of 20 MSPS. It features a high-performance sample-and-hold circuit and an on-chip voltage reference. The device utilizes a multistage differential pipeline architecture with output error correction logic to provide 10-bit accuracy without missing codes over the full operating temperature range. Key specifications include a signal-to-noise ratio (SNR) of 61.3 dBFS at a 9.7 MHz input frequency and a spurious-free dynamic range (SFDR) of 75 dBc under the same conditions. Power consumption is rated at 30 mW per channel at the 20 MSPS data rate.

Feature Summary

• Multistage differential pipeline architecture with output error correction logic ensures 10-bit accuracy and guarantees no missing codes across the full operating temperature range.
• Patented sample-and-hold circuit maintains excellent performance for input frequencies up to 200 MHz while supporting low cost and ease of use.
• Standard serial port interface supports configuration of product features including data output formatting, internal clock divider, power-down modes, and DCO/DATA timing adjustments.

Applications

• Communications systems
• Diversity radio systems
• Multimode digital receivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with the required industrial temperature range and verify that the LFCSP-64 footprint matches the design constraints. Cross-reference the datasheet revision to confirm all electrical parameters align with the intended application requirements before finalizing procurement.

Selection Notes

Select this component when a dual-channel, low-power ADC with a 20 MSPS sampling rate is required. The device accommodates both 1.8 V and 3.3 V logic families via a separate digital output driver supply. Consider the integrated voltage reference and sample-and-hold circuit if minimizing external component count is a priority. Verify that the differential input bandwidth and SNR specifications meet the system's signal integrity requirements.

Part Context

The AD9204 belongs to a family of dual-channel, 1.8 V, 10-bit analog-to-digital converters available in multiple speed grades, including 20 MSPS, 40 MSPS, 65 MSPS, and 80 MSPS variants. All members share the same 64-lead RoHS-compliant LFCSP package and pinout, facilitating migration between different speed grades within the same product line while maintaining consistent form factor and interface characteristics.

Replacement Considerations

Other speed grades within the AD9204 family, such as the AD9204BCPZ-40 or AD9204BCPZ-65, are pin-compatible alternatives offering higher sampling rates. These devices maintain the same package and interface but differ in maximum conversion speed and associated power consumption metrics.
