ADAV4201BSTZ

Overview

The AD9288BSTZ-40 is a dual-channel, 8-bit analog-to-digital converter (ADC) manufactured by Analog Devices. It operates at a sampling rate of 40 MSPS using a pipeline architecture. The device features differential inputs and a parallel CMOS/TTL interface. It requires analog and digital supply voltages between 2.7 V and 3.6 V. Key performance metrics include a signal-to-noise ratio (SNR) of 47.5 dB, differential nonlinearity (DNL) of 1.5 LSB, and integral nonlinearity (INL) of 1.5 LSB. Power consumption is specified at 156 mW typical, with a maximum power dissipation of 180 mW. It is housed in an LQFP-48 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel 8-bit resolution with 40 MSPS sampling rate
• Pipeline architecture with differential input capability
• Parallel CMOS/TTL output interface
• Low power consumption: 156 mW typical

Procurement Notes

Verify the specific ordering suffix and package variant against the manufacturer's current datasheet before procurement. Confirm that the LQFP-48 package dimensions and pinout match the target PCB footprint. Ensure voltage supply requirements align with the 2.7 V to 3.6 V specification for both analog and digital domains. Check for any moisture sensitivity level (MSL) handling requirements during storage and assembly.

Selection Notes

Select this component when a dual-channel, low-resolution, high-speed ADC is required. The 8-bit resolution and 40 MSPS speed suit applications where moderate precision and high throughput are needed. The parallel interface simplifies data transfer but may increase pin count compared to serial alternatives. Verify that the 47.5 dB SNR meets system noise floor requirements. Consider the LQFP-48 package size for board space constraints.

Part Context

This part belongs to the AD9288 series of dual ADCs from Analog Devices. It is distinct from other series like the AD9204 or audio codecs such as the ADAV4201. The 'BSTZ' suffix indicates the lead-free LQFP-48 package variant. The '-40' denotes the 40 MSPS speed grade. It is not related to DACs or audio processing ICs despite similar naming conventions in the broader product portfolio.
