The LTC1688CSPBF is part of the LTC1688 family of High-Speed, Low-Power, Sigma-Delta ADCs from Analog Devices. It is a 16-bit, 200kHz sigma-delta ADC that operates from a single +3.3 to +5.5V supply and is designed for high-speed, low-power applications. The architecture achieves low power, low noise and high dynamic performance in a tiny 7mm x 5mm package. It operates from a total supply current of just 4.5mA, has a 1.6MHz bandwidth, and can be clocked at up to 200kHz. It also features an on-chip bandgap reference, input/output spoofing, and a low-drift settling regulator. It has a differential input range of ±3.3V and an operating temperature range of -40°C to +85°C.
