The RES31A is a matched pair of resistive dividers, implemented in thin-film SiCr with Texas Instruments’ modern, high-performance, analog CMOS process. The device has a nominal input resistance of 100kΩ, supporting higher divider voltages than the RES11A but with a lower current draw than the RES21A, and is available in several nominal ratios to meet a wide array of system needs. Use the RES31A in an inverse gain configuration by simply rotating the device placement by 180°. This feature supports layout reuse and increases flexibility for applications such as discrete instrumentation or difference amplifier implementations.
The RES31A series features high ratio-matching precision, with the measured ratio of each divider within 0.05% (±500ppm) (typical) of the nominal. This precision is maintained over the temperature range.
The RES31A is specified with a temperature range from –40°C to +125°C. The device is offered in an 8‑pin, SOT‑23-THIN package, with a body size of 2.9mm × 1.6mm (body size is a nominal value and does not include pins).
