Product details
Overview
ISL95710UIU10Z-T from Intersil is a digitally controlled potentiometer (XDCP™) with 50kΩ end-to-end resistance, ±2.7V to ±5.5V terminal voltage range, 128 wiper tap positions, nonvolatile wiper position storage, and Up/Down interface - used for precision bias adjustment in analog signal chains and power supply feedback networks.
For engineers reviewing the ISL95710UIU10Z-T datasheet, ISL95710UIU10Z-T pinout, ISL95710UIU10Z-T application, or ISL95710UIU10Z-T equivalent, key selection criteria include wiper voltage range compatibility, nonvolatile recall behavior, MSOP-10 package constraints, and Up/Down timing requirements for system-level trim control.
Technical Context
The ISL95710UIU10Z-T implements a 127-element resistor array with make-before-break wiper switching, driven by a 7-bit up/down counter and decoded to select one of 128 tap points. Wiper position is stored in nonvolatile memory on CS↑ with INC HIGH and recalled at power-up.
It operates in dual-supply mode: VCC = +2.7V to +5.5V and V− = −2.7V to −5.5V, enabling true bipolar voltage divider operation. Standby current is 1µA, active current ≤3mA, and wiper resistance is 70–200Ω across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| End-to-end resistance | 50kΩ ±20% - defines full-scale adjustment range in rheostat or potentiometer configurations |
| Wiper tap count | 128 positions - provides 7.8mV/LSB resolution in 10V span voltage divider applications |
| Terminal voltage range | ±2.7V to ±5.5V - supports bipolar analog signal trimming without external level-shifting |
| Nonvolatile endurance | 200,000 store cycles - enables field calibration updates over product lifetime |
| Tempco (RTOTAL) | ±50ppm/°C - ensures <±0.4% resistance drift over −40°C to +85°C industrial range |
| Standby current | 1µA at VCC = 5.5V - minimizes quiescent power in always-on bias networks |
| Wiper resistance | 70–200Ω - contributes <0.4% gain error in high-impedance feedback paths |
Pinout & Package
ISL95710UIU10Z-T is housed in a 10-lead MSOP package (JEDEC MO-187BA, pkg drawing M10.118), RoHS-compliant with Pb-free anneal finish and 0.5mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 U/D | Direction control input | Determines wiper increment/decrement on each INC edge; logic level must be stable before INC transition |
| 2 V− | Negative analog supply | Bipolar reference for RH/RW/RL terminals; must ramp ≥−0.2V/ms to avoid spurious stores |
| 3 GND | Digital ground reference | Return path for CS/U/D/INC logic; isolated from analog V− but shares common system ground plane |
| 4 CS | Chip select / store trigger | LOW enables interface; HIGH with INC HIGH initiates nonvolatile store; must rise before VCC at power-up |
| 5 NC | No-connect terminal | Must remain unconnected - no internal connection or parasitic coupling |
| 6 RH | High fixed terminal | One end of resistor array; voltage polarity relative to RL depends on external circuit, not internal labeling |
| 7 RW | Wiper output | Movable terminal; exhibits 70–200Ω series resistance and ≤25pF capacitance to ground |
| 8 RL | Low fixed terminal | Other end of resistor array; forms voltage divider with RH when RW is used as output |
| 9 VCC | Positive logic/analog supply | +2.7V to +5.5V digital core and analog array bias; powers internal CMOS logic and switches |
| 10 INC | Edge-triggered increment | Negative-edge sensitive; minimum 1µs HIGH/LOW periods required for reliable wiper movement |
Key Features
| Feature | Design Value |
|---|---|
| Nonvolatile wiper storage | Retains last position for 50 years at ≤+75°C - eliminates boot-time re-trim in embedded systems |
| Make-before-break switching | Prevents open-circuit glitches during wiper transitions - critical for stable op-amp bias networks |
| Bipolar terminal voltage support | ±2.7V to ±5.5V operation - enables direct use in AC-coupled amplifiers and dual-rail power supplies |
| Low wiper resistance tempco | ±4ppm/°C ratiometric TCV - maintains voltage division accuracy independent of absolute resistance drift |
| Industrial temperature range | −40°C to +85°C operation - qualified for automotive cabin electronics and industrial PLC modules |

Equivalent & Alternatives
The following parts are listed as comparable options for similar digitally controlled potentiometer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ISL95310 | Same Up/Down interface, 10kΩ/50kΩ options, but 256-tap resolution and lower 0.5µA standby current | Higher resolution suits precision DAC replacement; lower power benefits battery-powered sensors | Preferred for new designs requiring finer adjustment granularity or extended battery life |
| AD5175BRMZ-50 | I²C interface, 256-tap, 50kΩ, ±2.7V to +5.5V (unipolar), no V− rail support | Requires I²C host and level-shifting for bipolar signals; lacks native negative supply capability | Only suitable where system already uses I²C and operates in unipolar domains |
Compared with ISL95710UIU10Z-T, ISL95310 offers higher resolution and lower power but identical pinout and interface; AD5175BRMZ-50 replaces Up/Down with I²C, eliminating bipolar support but adding addressability in multi-device systems.

FAQ
What is the maximum allowable voltage difference between RH and RL terminals for ISL95710UIU10Z-T?
The absolute maximum voltage difference ΔV = |V(RH) − V(RL)| is 12V per the Absolute Maximum Ratings table. This limit applies regardless of individual terminal voltages - for example, RH = +5.5V and RL = −5.5V yields 11V differential, which is within specification. Exceeding 12V risks permanent damage to the resistor array.
Does ISL95710UIU10Z-T support true bipolar operation, and how is it implemented?
Yes, ISL95710UIU10Z-T supports true bipolar operation via separate VCC (+2.7V to +5.5V) and V− (−2.7V to −5.5V) supplies. RH, RW, and RL terminals operate across this full ±5.5V range, enabling direct use in AC-coupled amplifiers and dual-rail power circuits without external level shifters or clamping diodes.
How does the nonvolatile store function work on ISL95710UIU10Z-T, and what timing is required?
The ISL95710UIU10Z-T stores the current wiper position in nonvolatile memory when CS transitions HIGH while INC is held HIGH. The minimum CS deselect time for store completion is 20ms (tCPHS). During this period, no INC or CS activity is permitted - violating this timing risks incomplete or corrupted storage.
What is the wiper resistance specification for ISL95710UIU10Z-T, and how does it affect circuit accuracy?
Wiper resistance (RW) is specified as 70Ω to 200Ω at VCC = +5.5V and V− = −5.5V. In voltage divider mode, this adds series resistance in the wiper path, causing gain error proportional to RW/(RH + RL). For a 50kΩ device, worst-case error is ~0.4%, which must be accounted for in high-accuracy feedback networks.
Is ISL95710UIU10Z-T pin-compatible with other members of the ISL95710 family, such as the ISL95710WIU10Z?
Yes, ISL95710UIU10Z-T is pin-compatible with ISL95710WIU10Z and all other ISL95710 variants in the 10-lead MSOP package. Both share identical pinout, interface timing, and electrical specifications - the only difference is end-to-end resistance (50kΩ vs. 10kΩ), which does not affect PCB layout or firmware.
