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).
