Product details
Overview
ADS6142IRHBR from Texas Instruments is a 14-bit, 65 MSPS analog-to-digital converter with DDR LVDS or parallel CMOS outputs, internal reference, and programmable coarse/fine gain. It delivers 74.6 dBFS SINAD at 10 MHz input (0 dB gain) and 84 dBc SFDR at 170 MHz (3.5 dB gain), targeting high-fidelity signal acquisition in software-defined radio and power amplifier linearization.
For engineers reviewing the ADS6142IRHBR datasheet, ADS6142IRHBR pinout, ADS6142IRHBR application, or ADS6142IRHBR equivalent, this page provides verified specifications, validated pin functions, confirmed industrial-temperature operation (–40°C to 85°C), package mapping to QFN-32 (5 mm × 5 mm), and two documented alternative parts for system-level design trade-offs.
Technical Context
The ADS6142IRHBR implements a high-bandwidth sample-and-hold with low-jitter clock buffer to maintain 71.5 dBFS SINAD at 170 MHz input under 3.5 dB coarse gain. Its dual-output interface supports DDR LVDS (3.3-V DRVDD, 100-Ω differential load) or parallel CMOS (1.8–3.3-V DRVDD), with programmable output clock position and drive strength to ease timing closure in FPGA-based data capture systems.
Configuration occurs via 3-wire serial interface (SEN/SCLK/SDATA) or dedicated parallel pins (SCLK/SEN/PDN) for power-up state control. Internal reference eliminates external decoupling; external reference mode supports 1.45–1.55 V common-mode voltage. Clock inputs accept sine, LVCMOS, LVPECL, or LVDS with amplitude down to 400 mVPP.
Key Specifications

FAQ
What is the maximum sampling rate supported by the ADS6142IRHBR?
The ADS6142IRHBR supports a maximum sampling rate of 65 MSPS, as specified in the TI SLWS198B datasheet. This rate is fixed for the ADS6142 variant and is lower than the 125 MSPS of the ADS6145, enabling optimized power efficiency at moderate bandwidths. The device maintains full 14-bit performance-including no missing codes and 74.6 dBFS SINAD-at this rated speed.
Does the ADS6142IRHBR require external decoupling capacitors for its internal reference?
No, the ADS6142IRHBR does not require external decoupling capacitors for its internal reference. As confirmed in the TI datasheet, the device integrates reference circuitry that eliminates traditional reference pins and associated external decoupling, simplifying PCB layout and reducing component count. External reference mode remains supported with 1.45–1.55 V common-mode voltage compliance.
Can the ADS6142IRHBR operate with a 1.8-V digital supply voltage?
Yes, the ADS6142IRHBR supports 1.8-V to 3.3-V digital supply (DRVDD) for CMOS interface operation. The datasheet specifies 1.65 V minimum for CMOS mode, and TI recommends 1.8 V DRVDD for easy migration to next-generation higher-speed devices. LVDS mode requires 3.3-V DRVDD and delivers 225–350 mV differential output voltage into 100-Ω loads.
What output interface options does the ADS6142IRHBR provide?
The ADS6142IRHBR offers two configurable output interfaces: DDR LVDS and parallel CMOS. Interface selection is controlled via the SEN pin in parallel mode or register 0x04 in serial mode. DDR LVDS operates at 3.3-V DRVDD with internal 100-Ω termination; CMOS supports 1.8–3.3-V DRVDD and programmable drive strength to match varying FPGA I/O standards and load capacitances.
Is the ADS6142IRHBR pin-compatible with other members of the ADS614X family?
Yes, the ADS6142IRHBR is pin-compatible with ADS6143IRHBR, ADS6144IRHBR, and ADS6145IRHBR-all housed in the same 32-pin QFN (RHB) package. This allows drop-in upgrades within the same footprint: for example, replacing ADS6142IRHBR with ADS6143IRHBR increases sample rate from 65 MSPS to 80 MSPS without PCB redesign, provided power and thermal constraints permit the higher 318 mW dissipation.
