AD9204BCPZRL7-65

Overview

The AD9204BCPZRL7-65 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 provide 10-bit accuracy without 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 a 200 MHz input frequency. The spurious-free dynamic range (SFDR) is specified at 75 dBc for a 9.7 MHz input and 73 dBc for a 200 MHz input. Differential nonlinearity (DNL) is ±0.11 LSB at 25°C, while integral nonlinearity (INL) is ±0.25 LSB at 25°C. The component operates within an ambient temperature range of −40°C to +85°C and is housed in a 64-lead LFCSP package.

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 data output formatting, internal clock divider, power-down modes, DCO/DATA timing adjustments, and voltage reference modes.
• Built-in selectable digital test pattern generation includes deterministic and pseudorandom patterns, along with custom user-defined test patterns entered via the serial port.

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 systems
• Battery-powered instruments and handheld scope meters
• Ultrasound, Radar/LIDAR, and PET/SPECT imaging

Procurement Notes

Verify the specific ordering suffix against official Analog Devices documentation to confirm the reel packaging format and exact speed grade. Ensure compatibility with the required logic family by checking the DRVDD supply voltage range. Confirm that the LFCSP-64 package thermal requirements are met through proper PCB ground plane connection for the exposed paddle.

Selection Notes

Select this component when a dual-channel, 10-bit ADC with a 65 MSPS sampling rate is required. Consider the 1.8 V analog supply and separate digital driver supply options for system power constraints. Evaluate the on-chip voltage reference and sample-and-hold circuit to determine if external components can be minimized. Verify that the SPI interface meets the system's control requirements for programmable clock alignment and data formatting.

Part Context

The AD9204BCPZRL7-65 belongs to the AD9204 series of dual-channel analog-to-digital converters from Analog Devices. This series offers multiple speed grades, including 20 MSPS, 40 MSPS, 65 MSPS, and 80 MSPS variants. All members share a common 64-lead RoHS compliant LFCSP package, facilitating pin compatibility with other high-resolution ADCs such as the AD9268, AD9251, AD9258, and AD9231 for migration purposes.

Replacement Considerations

The AD9204BCPZ-65 is a tray-packaged equivalent with identical electrical specifications. Other speed grades within the AD9204 family, such as AD9204BCPZ-40 or AD9204BCPZ-80, offer different sampling rates but maintain pin compatibility.
