DESCRIPTION

The TS7001 – a pin-for-pin, 1.5x faster alternate to the AD7887 – is a self-contained, 2-channel, high-speed, micropower, 12-bit analog-to-digital converter (ADC) that operates from a single +2.7V to +3.6V power supply. The TS7001 is capable of a 187.5-ksps throughput rate with an external 3MHz serial clock and draws 0.85mA supply current.

The wideband input track-and-hold acquires signals in 500ns and features a single-ended sampling topology. Output data coding is straight binary and the ADC is capable of converting full power signals up to 10 MHz. The ADC also contains an integrated 2.5V reference or the VREF pin can be overdriven by an external reference.

The TS7001’s provides one or two analog inputs each with an analog input range from 0 to VREF. In two-channel operation, the analog input range is 0V to VDD. Efficient circuit design ensures low power consumption of 2mW (typical) for normal operation and 3μW in power-down operation.

The TS7001 is fully specified from -40ºC to +85ºC and is available in 8-pin MSOP package.
