3 Description

The RES11A-Q1 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 1 kΩ, for low thermal and current

noise, and is available in several nominal ratios

to meet a wide array of system needs. Use the

RES11A-Q1 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-Q1 series features high ratio-matching

precision, with the measured ratio of each divider

within ±0.01 (typical) of the nominal. This precision

is maintained over the temperature range, with a

maximum ratio drift of only ±2 ppm/°C. Additionally,

the biased long-term stability of the device has been

proven through thorough characterization.

The RES11A-Q1 is automotive qualified under AECQ200

temperature grade 1. The temperature range is

specified from –40°C to +125°C. The device is offered

in an 8?pin, SOT?23-THIN package, with a body size

of 2.9 mm × 1.6 mm (body size is a nominal value and

does not include pins).
