Frequently asked questions
What is the difference between AD4115BCPZ and AD4115BCPZ-RL7?
The AD4115BCPZ and AD4115BCPZ-RL7 are the same Analog Devices AD4115 single-supply, 24-bit, sigma-delta ADC with ±10 V inputs. The suffix difference refers to packaging format: AD4115BCPZ is supplied in a 40-lead LFCSP (CP-40-9) tray, while AD4115BCPZ-RL7 is the same device supplied in tape and reel packaging (7-inch reel, 750 pieces per reel). Both share identical electrical specifications, temperature range, and functional performance.
Are AD4115BCPZ and AD4115BCPZ-RL7 electrically and functionally identical?
Yes. Both orderable part numbers refer to the same silicon die and package type (40-lead LFCSP, 6 mm × 6 mm). Analog Devices datasheet parameters such as resolution (24-bit), input range (±10 V), supply voltage (single 3.3 V or 5 V), and operating temperature range (−40°C to +105°C) apply equally to both. The only documented difference is the shipping container format.
Can AD4115BCPZ and AD4115BCPZ-RL7 be used interchangeably in a design?
Yes, from an electrical and footprint perspective they are interchangeable. Both use the same 40-lead LFCSP package with identical pinout and thermal characteristics. The choice between them is driven by manufacturing/procurement preferences: tray packaging for low-volume or prototype assembly, and tape and reel for automated high-volume pick-and-place production lines.
What is the package and pin count for AD4115BCPZ and AD4115BCPZ-RL7?
Both parts are housed in a 40-lead LFCSP (lead frame chip scale package) with exposed pad, designated CP-40-9 by Analog Devices. The package measures 6 mm × 6 mm with a 0.5 mm pitch. Pin assignments, exposed pad connection (typically to AVSS or as specified in the datasheet), and PCB land pattern requirements are identical for both orderable codes.
What is the difference in moisture sensitivity level (MSL) between AD4115BCPZ and AD4115BCPZ-RL7?
Both AD4115BCPZ and AD4115BCPZ-RL7 are rated at MSL 3 per JEDEC J-STD-020, as stated in the Analog Devices datasheet and product pages. MSL rating is a function of package construction and is not affected by tray versus tape and reel shipping format. Both require the same floor life and bake conditions before reflow.
Which part number should be used for automated production, AD4115BCPZ or AD4115BCPZ-RL7?
AD4115BCPZ-RL7 is the tape and reel option and is intended for automated pick-and-place assembly. AD4115BCPZ (tray) is typically used for prototyping, low-volume runs, or manual assembly. Both contain the same device; selection depends on the assembly process and reflow equipment compatibility with the carrier format.
Do AD4115BCPZ and AD4115BCPZ-RL7 share the same operating temperature range and accuracy specifications?
Yes. Both orderable part numbers are specified over the −40°C to +105°C industrial temperature range. Key ADC performance parameters such as 24-bit resolution, ±10 V input range, integral nonlinearity (INL), offset error, gain error, and noise specifications are identical because they are defined by the same silicon and package. Packaging format does not alter datasheet electrical characteristics.
Are AD4115BCPZ and AD4115BCPZ-RL7 RoHS compliant and lead-free?
Yes. Both AD4115BCPZ and AD4115BCPZ-RL7 are RoHS-compliant and lead-free, as indicated by the "Z" suffix in the part number, which denotes lead-free/RoHS-compliant construction per Analog Devices ordering guide. The tape and reel option (RL7) does not change the material compliance status of the device.
