The TPAFEA008 is an integrated product with 4-chnegative/positive output VDAC and 4-ch IDAC, which isoptimized for the optical module with 4-channel EML(Electro-absorption Modulated Laser).The VDAC in TPAFEA008 supports both negative andpositive output ranges, and the current capability is largeenough to bias EAM (Electro-Absorption Modulator).The IDAC in TPAFEA008 can support large output currentrange, and the output voltage range is also large enoughto support different laser diodes.The TPAFEA008 includes a 12bit ADC, with 4 input pins.Also, it incorporates internal alarm functions for ADC, so itcan be used for RSSI (Received Signal Strength Indicator)and LOS (Loss of Signal) detection.The VDAC output current and IDAC output voltage canbe monitored by an integrated 12-bit ADC, so it isconvenient for customers to monitor the loading status,without external components.The TPAFEA008 is featured with small size, highintegration, wide supply range, and operating temperaturerange, which make the device an excellent choice for 4-chEML optical modules.
