AD9204BCPZ-65

Overview

The AD9204BCPZ-65 is a monolithic, dual-channel, 1.8 V supply, 10-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 65 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 guarantee no missing codes over the full operating temperature range. Key electrical specifications include a Signal-to-Noise Ratio (SNR) of 61.3 dBFS at a 9.7 MHz input frequency and 61.0 dBFS at 200 MHz. Spurious-Free Dynamic Range (SFDR) reaches 75 dBc at 9.7 MHz and 73 dBc at 200 MHz. Differential Nonlinearity (DNL) is ±0.3 LSB, while Integral Nonlinearity (INL) is ±0.6 LSB. Power consumption is 125 mW at maximum sample rate with a 1.8 V digital supply.

Feature Summary

• Multistage differential pipeline architecture with output error correction logic for guaranteed linearity.
• Integrated sample-and-hold circuit and on-chip voltage reference for simplified system design.
• Programmable serial port interface (SPI) for configuration of data formatting, clock division, and power modes.
• Supports multiple digital output formats including offset binary, gray code, and two's complement.

Applications

• Communications systems including GSM, EDGE, W-CDMA, LTE, CDMA2000, WiMAX, and TD-SCDMA.
• Diversity radio systems and multimode digital receivers.
• I/Q demodulation systems and smart antenna arrays.
• Battery-powered instruments and handheld scope meters.
• Medical imaging applications such as ultrasound, Radar/LIDAR, and PET/SPECT.

Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's current ordering guide to confirm package type and RoHS compliance status. Ensure the required sampling speed variant matches the '-65' designation in the final part number. Confirm that the LFCSP-64 package thermal requirements are met by the target PCB layout, specifically regarding the exposed paddle connection to AGND.

Selection Notes

Select this component when a dual-channel, low-power 10-bit ADC is required for frequencies up to 200 MHz. The AD9204BCPZ-65 is suitable for designs needing a single 1.8 V analog supply and flexible 1.8 V to 3.3 V digital I/O levels. Consider the pin compatibility with other ADI converters like the AD9268 or AD9251 if future migration to higher resolution or speed is anticipated within the same footprint.

Part Context

The AD9204 series includes variants optimized for different sampling rates: 20 MSPS, 40 MSPS, 65 MSPS, and 80 MSPS. The AD9204BCPZ-65 specifically targets the 65 MSPS performance tier. All variants share the same 64-lead LFCSP package and functional block diagram, allowing for design flexibility across different bandwidth requirements while maintaining software and hardware compatibility.

Replacement Considerations

The SC9204 is documented as a compatible alternative offering similar performance characteristics and pinout compatibility.
