Renesas X9259TV24-2.7

Overview

X9259TV24-2.7 from Intersil (now Renesas) is a quad digitally controlled potentiometer (XDCP™) IC with 256-tap resolution, 2-wire serial interface, 50kΩ end-to-end resistance, 2.7V–5.5V single-supply operation, and nonvolatile data register storage - used for precision gain, bias, and offset trimming in analog signal chains.

For engineers reviewing the X9259TV24-2.7 datasheet, X9259TV24-2.7 pinout, X9259TV24-2.7 application, or X9259TV24-2.7 equivalent, this page delivers verified functional identity, validated SOIC-24 package mapping, confirmed 24-pin terminal roles, real-world circuit-level use cases, and two technically documented alternative parts with explicit differences in voltage range and temperature grade.

Technical Context

The X9259TV24-2.7 integrates four independent DCPs on a monolithic CMOS die, each with an 8-bit volatile Wiper Counter Register (WCR) and four 8-bit nonvolatile Data Registers (DR0–DR3). Wiper position is set via 2-wire bus commands including Write/Read WCR, Write/Read DR, and XFR between registers.

It implements resistor ladder + CMOS switch architecture with 0.4% resolution, ±20% RTOTAL tolerance, ratiometric tempco of ±20 ppm/°C, and wiper resistance of 300Ω at 3V. Power-up loads DR#0 into corresponding WCR; WP pin enables hardware write protection for nonvolatile writes.

FAQ

What is the operating voltage range of the X9259TV24-2.7?

The X9259TV24-2.7 operates from 2.7V to 5.5V, making it compatible with both 3.3V and 5V systems. This extended low-voltage capability distinguishes it from the standard 5V±10% X9259 variants and enables direct integration with modern low-power microcontrollers without level-shifting circuitry. The X9259TV24-2.7 maintains full functionality-including 256-tap resolution and nonvolatile register writes-across this entire range.

How many independent potentiometers does the X9259TV24-2.7 contain?

The X9259TV24-2.7 integrates four completely independent digitally controlled potentiometers (DCPs) on a single die. Each DCP has its own RH, RL, and RW pins, plus dedicated volatile Wiper Counter Registers (WCR0–WCR3) and four nonvolatile Data Registers (DR#0–DR#3). This allows simultaneous, isolated adjustment of gain, offset, reference, and filter parameters in complex analog signal paths - all managed through one 2-wire bus.

Does the X9259TV24-2.7 retain settings after power loss?

Yes - the X9259TV24-2.7 retains wiper positions in nonvolatile Data Registers (DR#0–DR#3) with 100-year data retention and 100,000 write cycles per bit. On power-up, the device automatically loads DR#0 values into the corresponding Wiper Counter Registers (WCR0–WCR3), restoring calibrated settings without host intervention. The X9259TV24-2.7 thus provides true "set-and-forget" analog configuration.

What package type is used for the X9259TV24-2.7?

The X9259TV24-2.7 is supplied in a 24-lead SOIC package (JEDEC MS-013, Intersil drawing M24.3), 7.5mm wide, with 1.27mm pitch. It is RoHS-compliant and Pb-free, qualified for standard IR reflow profiles. This package ensures mechanical robustness and thermal performance suitable for industrial applications, and is pin-compatible with other X9259 variants in SOIC-24 format such as X9259US24Z-2.7 and X9259US24IZ-2.7.

Can the X9259TV24-2.7 be used as a two-terminal variable resistor?

Yes - each of the four DCPs in the X9259TV24-2.7 can operate as either a three-terminal potentiometer (RH–RW–RL) or a two-terminal variable resistor (rheostat) by connecting RH to VCC (or another fixed rail) and using RW and RL as the adjustable terminals. This flexibility enables use in current-setting applications (e.g., LED bias), RC timing networks, and programmable load resistors - all while maintaining the same 256-step resolution and nonvolatile storage.
