There is also a discussion of the analog inputs, the seven sign comparators, three window comparators, the 8-bit Digital-to-Analog Converter (DAC), the reference voltage, grounding, and the supply voltage. 2.
! " # $% & & ! & ' &() *"& &+ *,$- + *,$ &./01 www.ti.com SBAS253E − MAY 2003 − REVISED JULY 2006 2.1.2 Window Comparator Inputs A sampling architecture was selected for the window comparators. The sampling time is two clock cycles with a minimum tAQ (see Equation 1) of 125ns. The necessary accuracy is 10mV (see 8-bit DAC section) with a 5V input range. The required bandwidth of the driving amplifier is 8.8MHz (see Equation 1).
! " # $% & & ! & ' &() *"& &+ *,$- + *,$ &./01 www.ti.com SBAS253E − MAY 2003 − REVISED JULY 2006 2.2.2 Clock The ADC uses the external clock CLK, which needs to be in the range of 1MHz to 16MHz. 12 clock cycles are necessary for a conversion, with a minimum of four clock cycles for the acquisition. Therefore, the maximum throughput rate of 1MSPS is achieved with a 16MHz clock and 16 clock cycles per complete conversion cycle.

! " # $% & & ! & ' &() *"& &+ *,$- + *,$ &./01 www.ti.com SBAS253E − MAY 2003 − REVISED JULY 2006 The input range of the comparators is limited. The lower voltage of the differential inputs should always be within the range of 0 to AVDD−1.8V. On every comparator, the output is delayed to the input voltage. This delay is dependent on the overdrive of the comparator inputs.
! " # $% & & ! & ' &() *"& &+ *,$- + *,$ &./01 www.ti.com SBAS253E − MAY 2003 − REVISED JULY 2006 2.4 Window Comparators The window comparators test if the input voltage is within a certain range; this range is ±(voltage applied to DAIN, pin 30). If the differential input voltage remains within this range, then the output of the window comparator is 1. If the voltage is outside this range, then the output is set to 0.
! " # $% & & ! & ' &() *"& &+ *,$- + *,$ &./01 www.ti.com SBAS253E − MAY 2003 − REVISED JULY 2006 2.5 8-Bit Digital-to-Analog Converter A voltage between 0.5V to 2.5V is required at DAIN (pin 30) to set the range of the window comparators; this can be accomplished with the 8-bit DAC. The DAC value is programmed via the digital interface. Input code 00H corresponds to a DAC output voltage of 0V.

The M1 and M0 pins determine in which mode the ADS7869 will communicate; see Table 1−1. It can be connected as a standard VECANA01 interface, as an SPI, or as two different parallel interfaces. Table 1−1.
! " # $% & & ! & ' &() *"& &+ *,$- + *,$ &./01 www.ti.com SBAS253E − MAY 2003 − REVISED JULY 2006 3.2 VECANA Interface The VECANA01 mode of the ADS7869 interface acts exactly like the original VECANA01 interface. This mode was added to the ADS7869 for backward-compatibility purposes. The VECANA01 interface is a proprietary serial interface with one serial input and three serial outputs.

" # $% & & ! & ' &() *"& &+ *,$- + *,$ &./01 www.ti.com SBAS253E − MAY 2003 − REVISED JULY 2006 The Gain Select portion (bits GAIN [1..0]) determines the programmable gain of the ADIN word; see Table 1−5. The gain for all three ADCs is set by one gain input parameter. The gain values and allowable full-scale inputs are shown in Table 1−4.

Data words: • Data path with a width of 16 bits is supported. 2. Bus handshaking: • Separate RD and WR style control signals. • Separate R/W and WE style control signals. 3. Mapping • The ADS7869 appears as a memory-mapped peripheral.
