RES31A
- Wide temperature range: –40°C to +125°C
- Ratio = RIN : RG, RIN = 100kΩ (nominal)
- Highly precise ratio tolerance: ±0.05% (maximum)
- Low drift over temperature range:
- +2/–5ppm/°C max TCRratio for RES31A00 (±2ppm/°C max TCRratio from –40°C to +105°C)
- ±2ppm/°C max TCRratio for other ratios
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).
