AD9236BCPZ-80

Overview

The AD9236BCPZ-80 is a monolithic, single 3 V supply, 12-bit, 80 MSPS analog-to-digital converter featuring a high-performance sample-and-hold amplifier (SHA) and voltage reference. It utilizes a multistage differential pipelined architecture with output error correction logic to provide 12-bit accuracy at 80 MSPS and guarantee no missing codes over the full operating temperature range. The device operates from a single 3 V power supply (2.7 V to 3.6 V) with a separate digital output driver supply (2.25 V to 3.6 V). Key performance metrics include an SNR of 70.4 dBc to Nyquist, SFDR of 87.8 dBc to Nyquist, DNL of ±0.4 LSB, and INL of ±0.35 LSB. Power consumption is 366 mW at low frequency input.

Procurement Notes

Verify the specific suffix 'BCPZ-80' against the manufacturer's current ordering guide to confirm package type, lead finish, and tape/reel specifications. Ensure the component meets RoHS compliance requirements if applicable to your manufacturing process. Cross-reference the datasheet revision to confirm all electrical parameters match your design specifications before finalizing procurement.

Selection Notes

Select this component when a 12-bit resolution and 80 MSPS sampling rate are required within a single 3 V supply system. Consider the LFCSP-32 package for space-constrained designs requiring efficient thermal dissipation via the exposed paddle. Evaluate the need for the on-chip reference versus external precision references based on system noise floor requirements and board space constraints.

Part Context

The AD9236 belongs to Analog Devices' family of high-speed, low-power ADCs. It is pin-compatible with the AD9215, AD9235, and AD9245, allowing simplified migration between different resolutions and speeds. The device is fabricated on an advanced CMOS process and is specified over the industrial temperature range of -40°C to +85°C.

Replacement Considerations

The AD9236BRU-80 is a pin-compatible alternative in a TSSOP-28 package. Other members of the AD9236 family, such as the AD9236BCPZRL7-80, offer identical electrical characteristics but may differ in packaging format or reel configuration.
