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

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 3

μW in power-down operation.

The TS7001 is fully specified from -40ºC to +85ºC

and is available in 8-pin MSOP package.

A Micropower, 2-channel, 187.5-ksps, Serial-Output 12-bit SAR ADC
