STMicroelectronics'16V op-amps

STMicroelectronics has announced 16V op-amps using an advanced manufacturing process that according to the company helps save energy, improve accuracy and simplify the design of sensors for applications from automotive electronics to smart buildings and industrial controls. The ICs are miniature amplifiers used to condition very small sensor signals, noted the company.

ST's op-amps claim to deliver better accuracy than existing devices, with greater long-term stability. The devices also have enhanced electro-static discharge protection, up to 4kV, and can operate from -40°C to 125°C allowing use in harsh industrial or automotive environments.

The TSX561, TSX562 and TSX564,containing one (single), two (dual) and four (quad) op-amps respectively, operate over a wide supply-voltage range from 3-16V, allowing use with a variety of industry-standard supply voltages such as 3V, 5V, 12V or ±5V.

The TSX56 series touts an input-offset voltage (max) of 600µV, 1pA input bias current and quiescent current (typical) of 240µA (at 5V). It has a gain-bandwidth (typical) of 900kHz, added the company. The devices come in a SOT23-5 (TSX561 single), DFN8 2 x 2mm, MiniSO-8 (TSX562 dual) and QFN16 3 x 3mm, TSSOP14 (TSX564 quad) packages.

The TSX56 series are in mass production priced from $0.50 depending on the configuration/package, in quantities of 1,000 units. Alternative pricing options for higher quantities are available on request.
