The TS4040 is a low power shunt voltage reference providing a stable 2.5V output voltage over the industrial temperature range (-40°C to +85°C). Available in SOT23-3 surface mount package, it can be designed in applications where space saving is critical. The low operating current is a key advantage for power restricted designs. In addition, the TS4040 is very stable and can be used in a broad range of application conditions.

Availabe in SOT23-3 surface mount package, it can be designed in applications where space saving is critical. The low operating current is a key advantage for power restricted designs. In addition, the TS4041 is very stable and can be used in a broad range of application conditions.

The TS4061 is a low power and high accuracy shunt voltage reference providing a stable output voltage over the industrial temperature range (-40 to +85 °C), with a maximum temperature coefficient of 35 ppm/°C. It is available in 0.1% and 0.2% initial accuracy versions. The SOT323-3L and SOT23-3L packages can be designed in applications where space saving is a critical issue. The very low operating current is a key advantage for power restricted designs. The TS4061 is very stable and can be used in a broad range of application conditions.

The TS419/TS421 is a monaural audio power amplifier driving in BTL mode a 16 or 32earpiece or receiver speaker. The main advantage of this configuration is to get rid of bulky ouput capacitors. Capable of descending to low voltages, it delivers up to 220mW per channel (into 16loads) of continuous average power with 0.2% THD+N in the audio bandwidth from a 5V power supply. An externally controlled standby mode reduces the supply current to 10nA (typ.). The TS419/TS421 can be configured by external gain-setting resistors or used in a fixed gain version.

Thanks to highly sensitive triggering levels, the device is suitable for all applications where the available gate current is limited, such as motor control for hand tools, kitchen aids, overvoltage crowbar protection for low power supplies among others. Available in through-hole and surface-mount packages, they provide an optimized performance in a limited space area.

The TS431 is a low-voltage, three-terminal, adjustable shunt voltage reference. The output voltage can be set to any value between Vref(1.24 V) and 6 V using two external resistors. The TS431 is able to operate at a lower voltage (1.24 V) and lower cathode current than the widely-used TL431 and TL1431 shunt voltage reference. When driving an optocoupler, the TS431 is particularly suitable for regulating 3.3 V switching power supplies.

The TS432 is an adjustable low power shunt voltage reference providing an output voltage from 1.24 V to 10 V over the industrial temperature range (-40° C to +85° C). Available in SOT23-3 surface mount package, it can be designed in applications where space saving is critical. The low operating current is also a key advantage for power restricted designs. In addition, the TS432 is very stable and can be used in a broad range of application conditions.

The TS4436 is a four-terminal device dedicated to low voltage Switch Mode Power Supplies (SMPS). It integrates a 0.6V voltage reference, an amplifier, and an open collector output transistor in a single package. The TS4436’s operating mode is similar to the well-known standard voltage reference, the TL431. It maintains the desired feedback voltage at the REF pin in a closed loop configuration by sinking a current proportional to the error voltage at the REF pin. TS4436 features an open collector transistor with an ultra-low saturation voltage. This feature allows it to be used in series with the optocoupler in an SMPS for regulation up to a 1.8V output voltage.

The TS46x are a family of operational amplifiers able to operate with voltages as low as ±1.35V and to reach a minimum of ±2Vpp of output swing when supplied with ±2.5V. This device is well-suited for all kinds of portable and battery-supplied equipment, where low noise and low distortion are key requirements. The TS461/2/4 offer excellent output rail-to-rail performance at an attractive cost.
