The RES21A-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 10kΩ, supporting higher divider voltages than the RES11A-Q1, and is available in several nominal
ratios to meet a wide array of system needs. Use the RES21A-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 RES21A-Q1 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 RES21A-Q1 is
automotive qualified under AEC-Q200 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 2.9mm × 1.6mm (body size is a nominal value and does
not include pins).
