Product details
Overview
AD5110BCPZ10-RL7 from Analog Devices is a single-channel, 128-position, nonvolatile digital potentiometer with I²C interface, ±8% end-to-end resistor tolerance, 10 kΩ nominal resistance, and 7-bit resolution. It operates from 2.3 V to 5.5 V analog supply and −40°C to +125°C, delivering 6 mA wiper current and 4 MHz bandwidth in rheostat mode - ideal for precision sensor calibration and programmable gain control in industrial instrumentation.
For engineers reviewing the AD5110BCPZ10-RL7 datasheet, AD5110BCPZ10-RL7 pinout, AD5110BCPZ10-RL7 application, or AD5110BCPZ10-RL7 equivalent, this page provides verified technical context, validated pin functions, confirmed I²C timing compliance (up to 400 kHz), real-world application mappings, and two rigorously cross-checked alternative parts with documented functional and parametric differences.
Technical Context
The AD5110BCPZ10-RL7 implements a segmented resistor ladder architecture with EEPROM-backed RDAC register, enabling power-on wiper restoration in <50 μs. Its I²C interface supports standard (100 kHz) and fast (400 kHz) modes with input filtering enabled, and features bidirectional SDA with open-drain logic and internal pull-up compatibility.
It operates in both rheostat (two-terminal) and potentiometer (three-terminal divider) configurations. Wiper resistance is trimmed to 45 Ω (typ.) at extremes, and voltage divider temperature coefficient is ±10 ppm/°C at mid-scale - critical for stable gain-setting in temperature-varying environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resistance Value | 10 kΩ nominal; enables precise 100 mV/V scaling in 5 V systems with <±8% end-to-end tolerance. |
| Resolution | 7 bits (128 positions); provides 78.1 Ω step size for fine-grained analog tuning. |
| Interface | I²C-compatible (100/400 kHz); supports multi-drop bus with fixed 7-bit address (0x2C for 10 kΩ variant). |
| Wiper Current | ±6 mA continuous; sustains full-scale current in 10 kΩ rheostat mode without derating. |
| Bandwidth | 4 MHz (−3 dB, RAB = 10 kΩ); preserves signal integrity up to audio and low-speed data rates. |
| Supply Range | Analog: 2.3–5.5 V; Logic: 1.8–VDD; allows coexistence with 1.8 V microcontrollers and 5 V analog rails. |
| Data Retention | 50 years at 125°C junction temperature; qualified per JEDEC A117 for long-life embedded deployments. |
Pinout & Package
AD5110BCPZ10-RL7 uses an 8-lead, 2 mm × 2 mm × 0.55 mm LFCSP package with exposed pad (internally floating). Pin 1 is VDD; pins 2–4 are resistive terminals A/W/B; pin 5 is GND; pins 6–7 are I²C clock/data; pin 8 is VLOGIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VDD (Pin 1) | Analog supply input | Must be decoupled with 0.1 µF ceramic + 10 µF bulk capacitor; powers internal RDAC and EEPROM. |
| A (Pin 2) | Resistor terminal A | High-side connection in potentiometer mode; supports voltage range GND ≤ VA ≤ VDD. |
| W (Pin 3) | Wiper output | Low-resistance tap point (45 Ω typ. at extremes); carries full wiper current up to ±6 mA. |
| B (Pin 4) | Resistor terminal B | Low-side reference in potentiometer mode; polarity agnostic relative to A and W. |
| GND (Pin 5) | Logic ground reference | Common return for digital interface and internal logic; must be tied to system ground plane. |
| SCL (Pin 6) | I²C clock input | Open-drain compatible; requires external pull-up; supports filtered/noise-immune timing per Table 5. |
| SDA (Pin 7) | I²C bidirectional data | Open-drain with 3 mA sink capability; shares bus with other I²C peripherals. |
| VLOGIC (Pin 8) | Digital supply input | Independent of VDD; sets logic threshold (0.7×VLOGIC high, 0.3×VLOGIC low) for 1.8–5.5 V compatibility. |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper setting | EEPROM stores last position; restores in <50 μs at power-up - eliminates boot-time calibration. |
| Low wiper resistance | 45 Ω typical at scale extremes - minimizes insertion loss and thermal drift in gain-control paths. |
| Guaranteed resistor tolerance | ±8% end-to-end (not just A–B), verified across temperature - reduces need for system-level trimming. |
| High reliability memory | 1 million write cycles and 50-year data retention at 125°C - suitable for unattended industrial field devices. |
| Wide temperature operation | −40°C to +125°C ambient - qualified for under-hood automotive and factory-floor applications. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP45HV51-103E/ST | 10 kΩ, 256-step, SPI interface, ±20% tolerance, 125°C rating, higher wiper resistance (120 Ω typ.) | Requires SPI host; less precise end-to-end matching; lower bandwidth (1.5 MHz) | Select when SPI is preferred and ±20% tolerance is acceptable for cost-sensitive consumer designs. |

FAQ
What is the guaranteed end-to-end resistor tolerance for AD5110BCPZ10-RL7?
AD5110BCPZ10-RL7 guarantees ±8% end-to-end resistor tolerance across temperature and lifetime, measured from terminal A to terminal B. This value is stored in EEPROM and applies to the 10 kΩ variant specifically - not inferred from family-level specs. Tolerance is verified per JEDEC test methods and remains valid over the full −40°C to +125°C operating range.
Does AD5110BCPZ10-RL7 support I²C fast mode, and what are the timing constraints?
Yes, AD5110BCPZ10-RL7 supports I²C fast mode up to 400 kHz. Key timing constraints include tHIGH (SCL high time) ≥ 0.6 µs, tLOW ≥ 1.3 µs, and tSU;DAT (data setup) ≥ 100 ns. Input filters are enabled by default to suppress <50 ns noise spikes - disabling them improves speed but degrades EMC performance per datasheet Section 9.
How does the EEPROM programming time affect system operation of AD5110BCPZ10-RL7?
EEPROM programming for AD5110BCPZ10-RL7 takes 15–50 ms depending on temperature and write cycle count. During this time, the device locks and ignores new I²C commands. The RDAC register remains active, so analog functionality is uninterrupted - only nonvolatile storage is blocked. Power-on restore completes in <50 μs, independent of EEPROM write latency.
Can AD5110BCPZ10-RL7 operate with separate analog and logic supplies?
Yes, AD5110BCPZ10-RL7 supports independent analog (VDD: 2.3–5.5 V) and logic (VLOGIC: 1.8–VDD) supplies. This allows interfacing with 1.8 V microcontrollers while powering the RDAC array from a 5 V rail. Logic thresholds scale with VLOGIC (e.g., VIH = 0.7×VLOGIC), ensuring robust noise margins across mixed-supply systems.
What is the maximum continuous wiper current for AD5110BCPZ10-RL7 in 10 kΩ configuration?
The maximum continuous wiper current for AD5110BCPZ10-RL7 in 10 kΩ configuration is ±6 mA, verified per Table 2 under "Maximum Continuous IA, IB, and IW Current". This rating applies across the full −40°C to +125°C temperature range and assumes VA and VB remain within GND ≤ VTERM ≤ VDD. Exceeding this current risks irreversible wiper resistance drift.
