ams News: Small ToF Proximity Sensor, Smartsens-ams GS Sensor Spec, 10K/15K Resolution Line Scan Imagers

BusinessWire: ams launches the TMD2636, a fully integrated proximity sensor which occupies 30% less space than currently available solutions, and so delivers transformational added value to manufacturers of True Wireless Stereo (TWS) earbuds.

The TMD2636 sensor module integrates a 940nm VCSEL, IR-sensing photodiodes, control circuitry, and a clear-mold overlay in a 2.0mm x 1.0mm x 0.35mm package. The sensor has an average active-mode current consumption of 70µA and 0.7µA in sleep mode. Central are the TMD2636 power-savings benefits, especially in the small battery capacity and size of a wireless earbud product.

Ams also publishes a fairly detailed spec of its Mira130 global shutter sensor, the fruit of its cooperation with Smartsens:

BusinessWire: ams also announces 10K and 15K resolution line-scan imagers. The new 4LS linear sensors feature four Red/Green/Blue/Clear channels scanning at up to 120,000 lines per second. Each of the four lines may be independently controlled and operated simultaneously for full-color image capture. Camera manufacturers can also implement 4:1 digital TDI, or to perform high-speed object inspection. In addition, the sensors offer the choice of either an 8-bit or 12-bit LVDS output to provide the most appropriate trade-off between image quality and speed. Full well-charge options range from 10 ke- to 40 ke- to enable use in a wide range of illumination conditions.

Pixel size in the new 4LS line scan image sensors is 5.6µm x 5.6µm. Dynamic range is up to 54dB, and quantum efficiency is 61% at 530nm.
