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).
