The TL103Wx features two high-voltage amplifiers and a shunt voltage reference to allow for cost-sensitive and compact battery charger CC/CV feedback circuits. The upgraded TL103WB features is designed to provide a wide supply range (up to 36V), low offset voltage (±0.3mV typical) and a 1.2MHz bandwidth. The integrated voltage reference is tied to the non-inverting pin of one of OP AMP 1 and provides a fixed 2.5V referenced to the negative supply of the device. The shunt reference of the TL103WA/TL103WB features a tight tolerance of 0.44% at 25°C.

When a single supply voltage of 5V is used (or ±2.5V split supply), the TL103Wx internal reference allows for a more accurate and power-efficient mid-supply signal to be used throughout your circuit. The TL103W/TL103WA devices are characterized for operation from -40°C to 85°C, the TL103WB devices are characterized for operation from –40°C to 125°C.
