Technical Guide: How to Select, Design In, and Use the AD5700-1BCPZ

When selecting the AD5700-1BCPZ for your design, consider its HART physical layer compliance, low power consumption, and integrated features. The device operates from a 2.7 V to 5.5 V supply, making it suitable for loop-powered 4-20 mA instruments where power budget is tight. Its 1 mA typical supply current allows coexistence with sensors and microcontrollers within the 3.5-4 mA loop budget. The internal oscillator eliminates the need for an external crystal, reducing component count and board space. The integrated receive band-pass filter can be bypassed if needed, and the HART output is internally buffered with high drive capability, simplifying the interface to the coupling network.

For design-in, ensure proper decoupling of the power supply and careful layout of analog and digital sections to minimize noise. The device requires a few external components, including a coupling capacitor and protection circuit for the HART signal path. Refer to the datasheet for detailed application circuits and recommended component values.

Frequently Asked Questions

You can buy AD5700-1BCPZ from authorized distributors including DigiKey, Mouser, and Octopart-listed suppliers. As of 2026-08-23, the AD5700-1BCPZ-R5 and AD5700-1BCPZ-RL7 tape-and-reel variants are listed on DigiKey and Mouser. The base AD5700-1BCPZ is also available through Analog Devices authorized channels. Contact XAIPART for stock availability and a formal quote.
Pricing for AD5700-1BCPZ varies by quantity, packaging, and distributor. No exact list price was captured in the verified web data as of 2026-08-23. For accurate bulk pricing, request a quote from XAIPART or check current stock and pricing on DigiKey and Mouser. The R5 and RL7 reel variants may have slightly different per-unit prices due to packaging quantity.
Lead time for AD5700-1BCPZ depends on distributor inventory and order quantity. DigiKey lists the AD5700-1BCPZ-R5 and AD5700-1BCPZ-RL7 as ship-today stock items for many quantities. For larger orders or the base tray version, typical lead time from Analog Devices is 6 to 8 weeks. Confirm current lead time with your distributor or XAIPART at the time of ordering.
The AD5700-1 includes an internal oscillator and does not require an external crystal or clock input, while the standard AD5700 requires an external 3.6864 MHz crystal or CMOS-level clock. Both are single-chip HART FSK half-duplex modems compliant with the HART physical layer, and both are available in the 24-lead LFCSP-WQ package. The AD5700-1 simplifies board design and reduces component count.
Choose AD5700-1BCPZ when you want to eliminate the external 3.6864 MHz oscillator, simplify layout, and reduce component count. This is especially useful in compact, loop-powered transmitters where board space and power budget are tight. Choose AD5700BCPZ only if you already have a system clock available, or if you prefer to use an external crystal for frequency control.
The best same-brand drop-in replacement is AD5700BCPZ, which shares the 24-lead LFCSP-WQ footprint but requires an external 3.6864 MHz oscillator. Cross-brand pin-compatible replacements include the HT5700 and HT1200M from Microcybers, which are advertised as pin-compatible alternatives to the AD5700 family. Always verify pinout and HART physical-layer compliance before substitution.
The AD5700/AD5700-1 datasheet (Rev. G) is available as a PDF directly from Analog Devices at https://www.analog.com/media/en/technical-documentation/data-sheets/AD5700_5700-1.pdf. It includes full electrical specifications, pinout, application circuits, and HART physical-layer compliance details. You can also access HTML and PDF versions through DigiKey and alldatasheet.
The AD5700-1BCPZ is a single-chip HART FSK half-duplex modem operating from 2.7V to 5.5V with 1 mA typical supply current. It has an integrated band-pass filter (bypassable), an internal 2.5V reference, an internal oscillator, and a buffered HART output with high drive capability. It operates from -40°C to +125°C in a 24-lead LFCSP-WQ (4x4 mm) package.
You can replace AD5700-1BCPZ with AD5700-1BCPZ-RL7 or AD5700-1BCPZ-R5 (same die, different reel packaging), or with AD5700BCPZ (requires external oscillator). Cross-brand pin-compatible replacements include the HT5700 and HT1200M HART modem chips from Microcybers. Always confirm the 24-lead LFCSP-WQ pinout and HART physical-layer compliance before substituting.
The best cross-brand equivalents are the HT5700 and HT1200M from Microcybers, which are marketed as pin-to-pin replacements for the AD5700 and A5191HRT HART modem families. They are HART-certified and mass-production ready, but their datasheets must be checked for exact parametric equivalence, especially oscillator and reference voltage behavior, before design-in.
The AD5700-1BCPZ and AD5700-1BCPZ-RL7 share the same silicon die and 24-lead LFCSP-WQ package. The only difference is the packaging and reel quantity: the -RL7 suffix indicates tape-and-reel on a 7-inch reel, while the base part is supplied as a standard bulk or tray option. Electrically they are identical.
The AD5700-1BCPZ operates from -40°C to +125°C, making it suitable for industrial process-control environments. According to the Analog Devices AD5700/AD5700-1 datasheet, the device also operates from a 2.7V to 5.5V supply and draws approximately 1 mA typical current. This combination supports deployment in harsh field-installed instruments.
Yes. The AD5700-1BCPZ's 1 mA typical operating current and 2.7V to 5.5V supply range make it suitable for loop-powered 4-20 mA instruments, where the total current budget is typically 3.5 to 4 mA. Its internal oscillator further reduces component count, preserving power budget for sensors and analog front-end circuits in the field instrument.
