The TLV1562 is a 10-bit CMOS low-power, high-speed programmable resolution analog-to-
digital converter based on a low -power recyclic architecture. The unique architecture delivers a
throughput up to 2 MSPS (million samples per second) at 10-bit resolution. The programmable
resolution allows a higher conversion throughput as a tradeoff of lower resolution. A high
speed 3-state parallel port directly interfaces to a digital signal processor (DSP) or
microprocessor (uP) system data bus. D0 through D9 are the digital output terminals with D0
being the least significant bit (LSB). The TLV1562 is designed to operate for a wide range of
supply voltages
(2.7 V to 5.5 V) with very low power consumption (11 mA maximum at 5.5 V, 10 MHz CLKIN).
The power saving feature is further enhanced with a software power -down feature (1 uA
maximum) and auto power-down (1 uA maximum) feature.
Many programmable features make this device a flexible general-purpose data converter. The
device can be configured as either four single -ended inputs to maximize the capacity or two
differential inputs to improve noise immunity. The internal system clock (SYSCLK) may come
from either an internally generated OSC or an external clock source (CLKIN). Four different
modes of conversion are available for different applications. The interrupt driven modes are
mostly suitable for asynchronous applications, while the continuous modes take advantage of
the high speed nature of a pipelined architecture. A pair of built-in sample-and-hold amplifiers
allow simultaneous sampling of two input channels. This makes the TLV1562 perfect for
communication applications. Conversion is started by the RD\ signal, which can also be used
for reading data, to maximize the throughput. Conversion can be started either by the RD\ or
CSTART\ signal when the device is operating in the interrupt-driven modes. The dedicated
conversion start pin, CSTART\, provides a mechanism to simultaneously sample and convert
multiple channels when multiple converters are used in an application.
The converter incorporates a pair of differential high-impedance reference inputs that facilitate
ratiometric conversion, scaling, and isolation of analog circuitry from logic and supply noise.
Other features such as low input capacitance (10 pF) and very wide input bandwidth (75 MHz)
make this device a perfect digital signal processing (DSP) companion for mobile
communication applications. A switched-capacitor design allows low -error conversion over the
full operating free-air temperature range.
The features that make this device truly a DSP friendly converter include: 1) programmable
continuous conversion modes, 2) programmable 2s complement output code format, and 3)
programmable resolution. The TLV1562 is offered in both 28-pin TSSOP and SOIC packages.
The TLV1562C is characterized for operation from 0°C to 70°C. The TLV1562I is characterized
