概述

Description

The AD7457BRTZ-REEL7 is an Analog Devices 12‑bit analog‑to‑digital converter (ADC) in a RoHS‑compliant BRTZ package, delivered on tape‑and‑reel (REEL7). It supports multiplexed input channels and a serial interface (SPI‑like) for easy integration into data‑acquisition, instrumentation, and control applications. The BRTZ suffix denotes the packaging variant, while REEL7 specifies tape‑and‑reel packaging. For exact electrical specs (sampling rate, input range, power supply, timing, and channel count), consult the AD7457 datasheet and packaging documentation.

Features

Here are core features of the AD7457BRTZ-REEL7:
- 12-bit, 8-channel multiplexed ADC (SAR architecture)
- Serial interface: SPI-compatible (SCLK, DIN, DOUT, CS)
- Throughput up to about 1 MSPS total with multiplexed channels
- On-chip sample-and-hold with input multiplexer and channel sequencing
- Wide supply range: 2.7 V to 5.25 V
- Industrial temperature range: -40 °C to +85 °C
- 16-lead package (RTZ) with RoHS-compliant reel packaging (REEL7)
- Monotonic operation with no missing codes across operating range
Note: Exact packaging and timing specifics are per the RTZ Reel7 configuration and device revision. For precise electrical characteristics, refer to the latest datasheet.

Package

It’s a 28-pin TSSOP package (TSSOP-28), RoHS-compliant, supplied on a 7-inch tape-and-reel (REEL7).

Pinout

- Pin count: 16 pins (package in AD7457BRTZ-REEL7 is a 16‑pin device, e.g., SOIC/TSSOP style in tape & reel).
- Function: 8‑channel, 12‑bit multiplexed ADC with a serial (SPI‑like) interface. It samples eight analog inputs (AIN0–AIN7) under a start/CONVST signal, and outputs the 12‑bit conversion result serially (DOUT) with data clocked in via SCLK. Interface pins include DIN, DOUT, SCLK, CS (and CONVST), plus power (VDD) and grounds (AGND/DGND) and reference (VREF) as applicable.

Manufacturer

Manufacturer: Analog Devices, Inc. (Analog Devices).
What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and digital signal processing integrated circuits.
