Texas Instruments ADC1175-50CIMTX/NOPB

Overview

ADC1175-50CIMTX/NOPB from Texas Instruments is an 8-bit, 50 MSPS analog-to-digital converter with internal track-and-hold, single +5V operation, and 125 mW typical power consumption. It delivers 6.8 effective bits at 25 MHz input frequency and supports straight binary output coding for video digitization and CCD imaging systems.

For engineers reviewing the ADC1175-50CIMTX/NOPB datasheet, ADC1175-50CIMTX/NOPB pinout, ADC1175-50CIMTX/NOPB application, or ADC1175-50CIMTX/NOPB equivalent, key selection considerations include its 7 pF input capacitance, 10 ps rms aperture jitter, power-down mode (<5 mW), industry-standard TSSOP/WQFN pinout, and reference ladder flexibility (VRT/VRB programmable from 1.0 V to 4.0 V range).

Technical Context

The ADC1175-50CIMTX/NOPB employs a flash-based architecture with integrated track-and-hold, sampling on the falling edge of CLK and delivering data after 2.5 clock cycles of pipeline latency. Its reference ladder accepts externally set or self-biased VRT (1.0–5.0 V) and VRB (0–4.0 V), enabling configurable full-scale ranges while maintaining ≤0.7 LSB DNL and ensured no missing codes.

Dynamic performance is optimized for video bandwidths: it achieves 43 dB SINAD and −54 dB THD at 24.9 MHz input with 50 MHz clock, supported by 120 MHz full-power analog input bandwidth and low 10 ps rms aperture jitter. The device operates across −20°C to +75°C and tolerates AVDD/DVDD mismatch <0.5 V.

Key Specifications

Pinout & Package

ADC1175-50CIMTX/NOPB is available in 24-pin TSSOP (PW package) and 24-pin WQFN (NHW0024B package), both rated for −20°C to +75°C operation. Pin functions are identical across packages; WQFN uses bottom-side thermal pad and different pin numbering per TI documentation.

FAQ

What is the operating temperature range for ADC1175-50CIMTX/NOPB?

The ADC1175-50CIMTX/NOPB is specified for operation from −20°C to +75°C, covering extended commercial environments such as portable digital cameras and industrial vision systems. This range is validated per TI's SNAS027G datasheet and applies to both TSSOP and WQFN package variants of ADC1175-50CIMTX/NOPB.

Does ADC1175-50CIMTX/NOPB support external reference voltage sources?

Yes, ADC1175-50CIMTX/NOPB supports external reference voltages applied directly to VRT (Pin 17) and VRB (Pin 23). The device accepts VRT from 1.0 V to AVDD and VRB from 0 V to 4.0 V, with VRT − VRB constrained to 1.0–2.8 V. External references must drive the 270 Ω reference ladder impedance and maintain low noise for optimal ENOB.

What is the minimum clock frequency supported by ADC1175-50CIMTX/NOPB?

The ADC1175-50CIMTX/NOPB supports a minimum conversion rate of 1 MHz per its AC Electrical Characteristics table. At lower clock frequencies, dynamic parameters like SINAD and THD remain valid, but pipeline latency (2.5 clock cycles) scales accordingly-enabling flexible timing in burst-mode or low-power acquisition scenarios using ADC1175-50CIMTX/NOPB.

How does the power-down mode affect the digital outputs of ADC1175-50CIMTX/NOPB?

When PD (Pin 1) is driven high, ADC1175-50CIMTX/NOPB enters power-down mode (<5 mW), and all D0–D7 outputs enter high-impedance TRI-STATE. Data becomes invalid within 140 ns of PD assertion. Upon exit (PD low), outputs resume normal operation after the same 140 ns wake-up delay-ensuring predictable interface behavior in ADC1175-50CIMTX/NOPB-based systems.

Can ADC1175-50CIMTX/NOPB be used with a 3.3 V digital interface?

No-ADC1175-50CIMTX/NOPB requires +4.75 V to +5.25 V on both AVDD and DVDD pins and is not 3.3 V I/O compatible. Its digital outputs swing rail-to-rail (0 V to DVDD), and VIH/VIL thresholds (2.0 V min / 0.8 V max) assume +5 V logic levels. Interfacing with 3.3 V FPGAs or processors requires level-shifting circuitry for ADC1175-50CIMTX/NOPB.
