SSP1606
The SSP1606 is 16-bit, simultaneous sampling, analog-to-digital data acquisition systems (DAS) with eight channels, respectively. Each part contains analog input clamp protection, a second-order antialiasing filter, a track-and-hold amplifier, a 16-bit charge redistribution successive approximation analog-to-digital converter (ADC), a flexible digital filter, a 2.5V reference and reference buffer, and high speed
serial and parallel interfaces.
The SSP1606 operate from a single 5V supply and can accommodate±10V and ±5V true bipolar input signals while sampling at throughput rates up to 200kSPS for all channels. The input clamp protection circuitry can tolerate voltages up to ±16.5V. The SSP1606 has 1MΩ analog input impedance regardless of sampling frequency. The single supply operation, on-chip filtering, and high input impedance eliminate the need for driver op amps and external bipolar supplies. The SSP1606 antialiasing filter has a 3dB cutoff frequency of 22.9kHz and provides 40dB antialias rejection when sampling at 200kSPS. The flexible digital filter is pin driven, yields improvements in SNR.
SSP584X
SSP584X series is a Quad-channel digital isolator, using chip level high voltage isolation process, isolation voltage up to 5KVrms. This series of products have low radiation, excellent anti-electromagnetic interference performance, high transmission rate and low power consumption; Equipped with enable pins to place the output in a high impedance state.
It has fail-safe mode, which can restore the output to the default state when the input power loss. This series of products have 4 in 0 out, 3 in 1 out, 2 in 2 out and other specifications, the specific product information, see the product selection table.
SSP721A
SSP721A is a single chip transceiver developed for Meter-Bus standard (EN1434-3、EN13757) applications.
The SSP721A interface circuit adjusts the different potentials between a slave system and the Meter-Bus master. The connection to the bus is polarity independent and supports full galvanic slave isolation with optocouplers. The circuit is supplied by the master via the bus. Therefore, this circuit offers no additional load for the slave battery. A power-fail function is integrated. The receiver has dynamic level recognition, and the transmitter has a programmable current sink. A 3.3V voltage regulator, with power reserve for a delayed switch off at bus fault, is integrated.
