Product details
Overview
TLV1562CDWR from Texas Instruments is a 10-bit reconfigurable analog-to-digital converter with dual sample-and-hold, 4-input multiplexer, parallel interface, and software-selectable power-down mode. It delivers up to 2 MSPS at 10-bit resolution (±1 LSB INL/DNL), operates from 2.7 V to 5.5 V, and supports single-ended or differential input configurations for portable communication systems.
For engineers reviewing the TLV1562CDWR datasheet, TLV1562CDWR pinout, TLV1562CDWR application, or TLV1562CDWR equivalent, key selection criteria include programmable resolution (4/8/10-bit), simultaneous dual-channel sampling capability, 75 MHz analog input bandwidth, interrupt- or continuous-mode conversion control, and low-power operation (11 mA max at 5.5 V, 1 µA in software power-down).
Technical Context
The TLV1562CDWR implements a low-power recyclic ADC architecture delivering 2 MSPS at 10-bit resolution using 5 system clock cycles per conversion. It integrates two matched sample-and-hold amplifiers enabling true simultaneous sampling of two channels - critical for phase-coherent signal acquisition in communications receivers.
Its programmable configuration includes four conversion modes (mono/dual interrupt, mono/dual continuous), selectable input type (2 differential or 4 single-ended), 2's complement/binary output format, and internal/external clock source. The device uses a 10-bit parallel interface with RD/WR/CS/OE control signals and generates an INT signal upon conversion completion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | Programmable 4-, 8-, or 10-bit; enables throughput/resolution tradeoff (7 MSPS @ 4-bit, 2 MSPS @ 10-bit) |
| Max Throughput | 2 MSPS at 10-bit (single channel, continuous mode); supports real-time digitization of baseband IF signals |
| INL / DNL | ±1 LSB max at 10-bit; ensures monotonicity and accurate amplitude representation without missing codes |
| Analog Input Bandwidth | 75 MHz (–1 dB), >120 MHz (–3 dB) at Rs = 1 kΩ; supports undersampling of IF signals up to 800 kHz Nyquist zone |
| Power Consumption | 11 mA at 5.5 V / 10 MHz; drops to 1 µA in software power-down - extends battery life in portable radios |
| Reference Interface | Differential VREFP/VREFM inputs (0.8 V to 3 V span); enables ratiometric measurement and noise rejection |
| Sample-and-Hold | Dual matched S/H with simultaneous capture; eliminates inter-channel timing skew in multi-signal systems |
Pinout & Package
TLV1562CDWR is packaged in a 28-pin SOIC (DW) with 50-mil pitch, rated for 0°C to 70°C operation. Pin functions are validated per TI SLAS162 datasheet (September 1998).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CSTART | Conversion start trigger | Falling edge initiates sampling; rising edge starts conversion - enables synchronized multi-ADC acquisition |
| D0–D9 | Parallel data bus | 10-bit bidirectional outputs (D0 = LSB); 3-state controlled by CS/OE and RD/WR for direct DSP/microprocessor interfacing |
| RD | Read strobe / conversion trigger | Falling edge starts conversion in mono modes; rising edge reads data and tri-states bus - reduces interface latency |
| INT | Interrupt output | Active-low open-drain signal asserts after conversion completes; synchronizes host processor data capture |
| AP/CH1, AM/CH2, BP/CH3, BM/CH4 | Analog input terminals | Configurable as 4 single-ended (CH1–CH4) or 2 differential pairs (A: AP/AM, B: BP/BM) via CR0 bit 4 |
| VREFP / VREFM | Reference voltage inputs | Differential reference pair sets full-scale range; supports ratiometric sensing and isolation from supply noise |
| AVDD, DVDD, BDVDD | Supply rails | Separate analog (AVDD), core digital (DVDD), and I/O buffer (BDVDD) supplies - minimize digital switching noise coupling |
| AGND, DGND, BDGND | Ground returns | Independent analog, digital logic, and I/O ground pins - preserve signal integrity in mixed-signal layouts |
Key Features
| Feature | Design Value |
|---|---|
| Reconfigurable resolution | Runtime-selectable 4/8/10-bit modes via control registers - optimizes speed vs. precision per application need |
| Dual simultaneous S/H | Matched pair enables phase-aligned sampling of two channels - essential for I/Q demodulation and motor current sensing |
| Software power-down | 1 µA standby current via register write - preserves battery charge during idle periods in portable devices |
| Programmable conversion modes | Four modes (mono/dual interrupt, mono/dual continuous) - balances latency, throughput, and CPU load in embedded systems |
| Built-in calibration | On-chip offset calibration (system or internal) - maintains accuracy across temperature and supply variations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-power ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC5510IPW | 8-bit, 20 MSPS, no S/H, no power-down, CMOS parallel interface | Lacks dual S/H, programmable resolution, and sleep mode - unsuitable for battery-powered or multi-channel sync apps | Choose when raw speed > power efficiency and single-channel sampling suffices |
| ADS7822U | 12-bit, 200 kSPS, SPI interface, single S/H, 1.2 mW typical power | Lower throughput, serial interface, no dual S/H - better for low-speed sensor nodes than comms front-ends | Prefer for ultra-low-power sensor logging where 12-bit resolution and SPI simplify layout |
Compared with TLC5510IPW and ADS7822U, the TLV1562CDWR uniquely combines programmable resolution, dual simultaneous sampling, and sub-µA power-down - making it the only option among the three for portable radios requiring phase-coherent, battery-efficient digitization.

FAQ
What is the maximum sampling rate of the TLV1562CDWR at full 10-bit resolution?
The TLV1562CDWR achieves up to 2 million samples per second (MSPS) at 10-bit resolution in mono continuous mode with external 10 MHz clock. This throughput is guaranteed with ±1 LSB integral nonlinearity and differential nonlinearity, enabling accurate digitization of baseband signals in portable radios and motor control systems. Performance remains stable across the 0°C to 70°C operating range specified for the TLV1562CDWR.
Does the TLV1562CDWR support simultaneous sampling of two analog channels?
Yes, the TLV1562CDWR integrates two matched sample-and-hold amplifiers that enable true simultaneous sampling of two input channels - either two single-ended signals (e.g., CH1 and CH3) or one differential pair (e.g., AP/AM). This capability is activated in dual interrupt or dual continuous conversion modes and is confirmed in the functional block diagram and timing specifications of the TLV1562CDWR datasheet.
How does the power-down feature work on the TLV1562CDWR?
The TLV1562CDWR offers two power-down mechanisms: software power-down (1 µA max) triggered by writing to CR1 bit 0, and auto power-down (120 µA max) enabled in interrupt-driven modes. Both reduce current draw significantly versus active operation (11 mA at 5.5 V). The software mode retains register state and requires no hardware reset, making it ideal for rapid wake-up in battery-powered TLV1562CDWR applications like pagers and scanners.
Can the TLV1562CDWR operate from a single 3.3 V supply?
Yes, the TLV1562CDWR supports a single wide-range supply from 2.7 V to 5.5 V DC. At 3.3 V, it delivers 1.6 MSPS at 10-bit resolution (industrial temp) and 2 MSPS (commercial temp), with supply current reduced to approximately 8.5 mA. All analog input ranges, reference compliance, and timing specifications remain valid within this supply range - verified in the "Electrical Characteristics" section of the TLV1562CDWR datasheet.
What interface protocol does the TLV1562CDWR use for host processor communication?
The TLV1562CDWR uses a DSP/microprocessor-compatible 10-bit parallel interface with dedicated RD (read strobe), WR (write strobe), CS/OE (chip select/output enable), and INT (interrupt) signals. Data appears on D0–D9 (D0 = LSB) and is 3-stated when RD or CS is inactive. This interface allows direct connection to standard microcontroller data buses without glue logic - a key design feature confirmed in the TLV1562CDWR functional description and timing diagrams.
