TPAFEA008 Datasheet | 3PEAK

Features - 4-Channel 12-Bit Voltage Output DAC - Positive and Negative Output Range: - 5 V, - 2.5 V, 2.5 V, 5 V - High Output Capability: 60 m A - 4-Channel 12-Bit Current Output DAC - 200-m A Output Range - 12-Bit ADC - 4 External Inputs - VDAC Current Monitor - Internal Reference - 2.5 V - Serial Interfaces - 4 Wire SPI - I2C with 4 Slave Addresses - Temperature Range: - 40°C to +125°C - Package: Wafer-Level CSP Applications - High-Speed Optical Module Description The TPAFEA008 is an integrated product with 4-ch negative/positive output VDAC and 4-ch IDAC, which is optimized for the optical module with 4-channel EML (Electro-absorption Modulated Laser). The VDAC in TPAFEA008 supports both negative and positive output ranges, and the current capability is large enough to bias EAM (Electro-Absorption Modulator). The IDAC in TPAFEA008 can support large output current range, and the output voltage range is also large enough to support different laser diodes. The TPAFEA008 includes a 12bit ADC, with 4 input pins. Also, it incorporates internal alarm functions for ADC, so it can be used for RSSI (Received Signal Strength Indicator) and LOS (Loss of Signal) detection. The VDAC output current and IDAC output voltage can be monitored by an integrated 12-bit ADC, so it is convenient for customers to monitor the loading status, without external ponents. The TPAFEA008 is featured with small size, high integration, wide supply range, and operating temperature range, which make the device an excellent choice for 4-ch EML optical modules.
