description
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 (
P) 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
A maximum) and auto power-down (1 A
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.
