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).
