3 Description
The RES11A 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 1kΩ,
for low thermal and current noise, and is available
in several nominal ratios to meet a wide array
of system needs. Use the RES11A 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 RES11A series features high ratio-matching
precision, with the measured ratio of each divider
within ±0.05% (±500ppm) of the nominal. This
precision is maintained over the temperature range,
with a maximum ratio drift of only ±2ppm/°C.
Additionally, the biased long-term stability of
the device has been proven through thorough
characterization.
The RES11A 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).
