Overview
The AD9235BCPZRL7-40 is a monolithic, single-supply, 12-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 40 MSPS. It utilizes a multistage differential pipelined architecture with output error correction logic to ensure no missing codes across the industrial temperature range (-40°C to +85°C). The device features an integrated high-performance sample-and-hold amplifier (SHA) and voltage reference, powered by a single 3 V supply (2.7 V to 3.6 V). It consumes 180 mW at full speed with a sine wave input. The component is housed in a 32-lead LFCSP package.
Feature Summary
- Integrated high-performance sample-and-hold amplifier (SHA) and internal voltage reference
- Multistage differential pipelined architecture with output error correction logic
- Single 3 V power supply operation with separate digital driver supply
- Flexible analog input configuration supporting both differential and single-ended modes
Applications
- Ultrasound equipment
- IF sampling in communications receivers
- Battery-powered instruments
- Hand-held scopemeters
- Low cost digital oscilloscopes
Procurement Notes
Verify the specific ordering suffix RL7 corresponds to the reel packaging format when sourcing components. Confirm that the BCPZ designation indicates lead-free RoHS-compliant construction compatible with standard surface-mount assembly processes. Ensure the -40 speed grade matches the required system throughput specifications before finalizing procurement orders.
Selection Notes
Select this model for applications requiring 12-bit resolution at up to 40 MSPS within a compact footprint. The LFCSP package offers thermal advantages over TSSOP options. Consider the internal reference capabilities to simplify board design, or utilize external references if higher precision is required. Verify compatibility with the target logic family using the DRVDD pin.
Part Context
The AD9235 series includes variants operating at 20 MSPS, 40 MSPS, and 65 MSPS. The AD9235BCPZRL7-40 specifically denotes the 40 MSPS version in the 32-lead LFCSP package. This part shares architectural similarities with the AD9214 and AD9215 families, allowing for potential pin-compatible upgrades from lower-resolution systems.
Replacement Considerations
The AD9235BRUZ-40 serves as a direct functional replacement in the 28-lead TSSOP package. For systems requiring higher speeds, the AD9235-65 variant is available. Lower-speed requirements may be met by the AD9235-20 model.
