ADC Single 2.8Msps 12-bit Parallel 48-Pin LQFP, MAX1305ECM+, Maxim Integrated

Описание

The MAX1304–MAX1306/MAX1308–MAX1310/MAX1312–MAX1314 12-bit, analog-to-digital converters (ADCs) offer eight, four, or two independent input channels. Independent track-and-hold (T/H) circuitry provides simultaneous sampling for each channel. The MAX1304/MAX1305/MAX1306 provide a 0 to +5V input range with ±6V fault-tolerant inputs. The MAX1308/MAX1309/MAX1310 provide a ±5V input range with ±16.5V fault-tolerant inputs. The MAX1312/MAX1313/MAX1314 have a ±10V input range with ±16.5V fault-tolerant inputs. These ADCs convert two channels in 0.9µs, and up to eight channels in 1.98µs, with an 8-channel throughput of 456ksps per channel. Other features include a 20MHz T/H input bandwidth, internal clock, internal (+2.5V) or external (+2.0V to +3.0V) reference, and power-saving modes. A 20MHz, 12-bit, bidirectional parallel data bus provides the conversion results and accepts digital inputs that activate each channel individually. All devices operate from a +4.75V to +5.25V analog supply and a +2.7V to +5.25V digital supply and consume 57mA total supply current when fully operational. Each device is available in a 48-pin 7mm x 7mm LQFP package and operates over the extended -40°C to +85°C temperature range.
